-Ein paar Hinweise für die korrekte Formatierung des Textes
-\begin{itemize}
-\item
-Absätze werden gebildet, indem man eine Leerzeile einfügt.
-Die Verwendung von \verb+\\+ ist nur in Tabellen und Arrays gestattet.
-\item
-Die explizite Platzierung von Bildern ist nicht erlaubt, entsprechende
-Optionen werden gelöscht. 
-Verwenden Sie Labels und Verweise, um auf Bilder hinzuweisen.
-\item
-Beginnen Sie jeden Satz auf einer neuen Zeile. 
-Damit ermöglichen Sie dem Versionsverwaltungssysteme, Änderungen
-in verschiedenen Sätzen von verschiedenen Autoren ohne Konflikt 
-anzuwenden.
-\item 
-Bilden Sie auch für Formeln kurze Zeilen, einerseits der besseren
-Übersicht wegen, aber auch um GIT die Arbeit zu erleichtern.

+\section{Ausgangslage\label{0f1:section:ausgangslage}}
+\rhead{Ausgangslage}
+Die Hypergeometrische Funktion $\mathstrut_0F_1$ wird in vielen Funktionen als Basisfunktion benutzt, 
+zum Beispiel um die Airy Funktion zu berechnen. 
+In der GNU Scientific Library \cite{library-gsl} 
+ist die Funktion $\mathstrut_0F_1$ vorhanden. 
+Allerdings wirft die Funktion, bei negativen Übergabenwerten wie zum Beispiel \verb+gsl_sf_hyperg_0F1(1, -1)+, eine Exception. 
+Bei genauerer Untersuchung hat sich gezeigt, dass die Funktion je nach Betriebssystem funktioniert oder eben nicht. 
+So kann die Funktion unter Windows fehlerfrei aufgerufen werden, beim Mac OS und Linux sind negative Übergabeparameter im Moment nicht möglich.
+Ziel dieser Arbeit war es zu evaluieren, ob es mit einfachen mathematischen Operationen möglich ist, die Hypergeometrische Funktion $\mathstrut_0F_1$ zu implementieren.

+\subsection{Hypergeometrische Funktion $\mathstrut_0F_1$
+\label{0f1:subsection:0f1}}
+Wie in Kapitel \ref{buch:rekursion:section:hypergeometrische-funktion} beschrieben,
+wird die Funktion $\mathstrut_0F_1$ folgendermassen definiert.
+\begin{definition}
+    \label{0f1:rekursion:hypergeometrisch:def}
+    Die hypergeometrische Funktion
+    $\mathstrut_0F_1$ ist definiert durch die Reihe
+    \[
+    \mathstrut_0F_1
+    \biggl(
+    \begin{matrix}
+    \\
+    b_1
+    \end{matrix}

+    x
+    \biggr)
+    =
+    \mathstrut_0F_1(;b_1;x)
+    =
+    \sum_{k=0}^\infty
+    \frac{1}{(b_1)_k}\frac{x^k}{k!}.
+    \]
+\end{definition}
+
+
+\subsection{Airy Funktion
+\label{0f1:subsection:airy}}
+Wie in \ref{buch:differentialgleichungen:section:hypergeometrisch} dargestellt, ist die Airy-Differentialgleichung
+folgendermassen definiert.
+\begin{definition}
+    y'' - xy = 0
+    \label{0f1:airy:eq:differentialgleichung}
+\end{definition}
+
+Daraus ergibt sich wie in Aufgabe~\ref{503} gefundenen Lösungen der
+Airy-Differentialgleichung als hypergeometrische Funktionen.

+\rhead{Resultate}
+Im Verlauf des Seminares hat sich gezeigt, 
+das ein einfacher mathematischer Algorithmus zu implementieren gar nicht so einfach ist.
+So haben alle drei umgesetzten Ansätze Probleme mit grossen negativen x in der Funktion $\mathstrut_0F_1(;b;x)$.
+Ebenso wird, je grösser der Wert x wird $\mathstrut_0F_1(;b;x)$, desto mehr weichen die berechneten Resultate
+von den erwarteten ab.

+für $\nu = z - 1$ entspricht.

+\end{enumerate}
+Die erste Variante wäre optimal auf das Problem angepasst,
+allerdings müssten die Gewichte und Nullstellen für jedes $z$
+neu berechnet werden,
+da sie per Definition von $z$ abhängen.
+Dazu kommt,
+dass die Berechnung der Gewichte $A_i$ nach
+\cite{laguerre:Cassity1965AbcissasCA}
 \begin{align*}
+A_i
+=
+\frac{
+\Gamma(n) \Gamma(n+\nu)
+}
+{
+(n+\nu)
+\left[L_{n-1}^{\nu}(x_i)\right]^2
+}
+\end{align*}
+Evaluationen der Gamma-Funktion benötigen.
+Somit ist diese Methode eindeutig nicht geeignet für unser Vorhaben.
+
+Bei der zweiten Variante benötigen wir keine Neuberechung der Gewichte
+und Nullstellen für unterschiedliche $z$.
+In \eqref{laguerre:quadratur_gewichte} ist ersichtlich,
+dass die Gewichte einfach zu berechnen sind.
+Auch die Nullstellen können vorgängig,
+mittels eines geeigneten Verfahrens,
+aus den Polynomen bestimmt werden.
+Als problematisch könnte sich höchstens
+die zu integrierende Funktion $f(x)=x^{z-1}$ für $|z| \gg 0$ erweisen.
+Somit entscheiden wir uns aufgrund der vorherigen Punkte,
+die zweite Variante weiterzuverfolgen.

+%.
+Wenden wir also die Gauss-Laguerre-Quadratur aus
+\eqref{laguerre:laguerrequadratur} auf die Gamma-Funktion
+\eqref{laguerre:gamma} an,
+ergibt sich
+\begin{align}
+\Gamma(z)
+\approx
+\sum_{i=1}^n x_i^{z-1} A_i
+\label{laguerre:naive_lag}
+.
+\end{align}
+Bevor wir die Gauss-Laguerre-Quadratur anwenden,
+möchten wir als ersten Schritt eine Fehlerabschätzung durchführen.
+Für den Fehlerterm \eqref{laguerre:lag_error} wird die $2n$-te Ableitung
+der zu integrierenden Funktion $f(\xi)$ benötigt.
+Für das Integral der Gamma-Funktion ergibt sich also
+\begin{align*}
+\frac{d^{2n}}{d\xi^{2n}} f(\xi)
+ & =
+\frac{d^{2n}}{d\xi^{2n}} \xi^{z-1}
+\\
+ & =
+(z - 2n)_{2n} \xi^{z - 2n - 1}
+.
+\end{align*}
+Eingesetzt im Fehlerterm \eqref{laguerre:lag_error} resultiert
+\begin{align}
 R_n
 =
 (z - 2n)_{2n} \frac{(n!)^2}{(2n)!} \xi^{z-2n-1}
-\end{align*}
+,
+\label{laguerre:gamma_err_simple}
+\end{align}
+wobei $\xi$ ein geeigneter Wert im Intervall $(0, \infty)$ ist
+und $n$ der Grad des verwendeten Laguerre-Polynoms.
+Eine Fehlerabschätzung mit dem Fehlerterm stellt sich als unnütz heraus,
+da $R_n$ für $z < 2n - 1$ bei $\xi \rightarrow 0$ eine Singularität aufweist
+und für $z > 2n - 1$ bei $\xi \rightarrow \infty$ divergiert.
+Nur für den unwahrscheinlichen Fall $ z = 2n - 1$
+wäre eine Fehlerabschätzung plausibel.
 
-\subsubsection{Finden der optimalen Berechnungsstelle}
+Wenden wir nun also direkt die Gauss-Laguerre-Quadratur
+auf die Gamma-Funktion an.
+Dazu benötigen wir die Gewichte nach
+\eqref{laguerre:quadratur_gewichte}
+und als Stützstellen die Nullstellen des Laguerre-Polynomes $L_n$.
+Evaluieren wir den relativen Fehler unserer Approximation zeigt sich ein
+Bild wie in Abbildung~\ref{laguerre:fig:rel_error_simple}.
+Man kann sehen,
+wie der relative Fehler Nullstellen aufweist für ganzzahlige $z \leq 2n$.
+Laut der Theorie der Gauss-Quadratur ist das auch zu erwarten,
+da die Approximation via Gauss-Quadratur
+exakt ist für zu integrierende Polynome mit Grad $\leq 2n-1$ und
+der Integrand $x^{z-1}$ wird für $z \in \mathbb{N} \setminus \{0\}$
+zu einem Polynom .
+% Hinzukommt, dass zudem von $z$ noch $1$ abgezogen wird im Exponenten.
+Es ist ersichtlich,
+dass sich für den Polynomgrad $n$ ein Intervall gibt,
+in dem der relative Fehler minimal ist.
+Links steigt der relative Fehler besonders stark an,
+während er auf der rechten Seite zu konvergieren scheint.

+für verschiedene reelle Werte von $z$ und Grade $n$ der Laguerre-Polynome}
+\label{laguerre:fig:rel_error_mirror}
+\end{figure}
+
+Um die linke Hälfte in den Griff zu bekommen,
+könnten wir die Reflektionsformel der Gamma-Funktion verwenden.
+Spiegelt man nun $z$ mit negativem Realteil mittels der Reflektionsformel,
+ergibt sich ein stabilerer Fehler in der linken Hälfte,
+wie in Abbildung~\ref{laguerre:fig:rel_error_mirror}.
+Die Spiegelung bringt nur für wenige Werte einen,
+für praktische Anwendungen geeigneten,
+relativen Fehler.
+Wie wir aber in Abbildung~\ref{laguerre:fig:rel_error_simple} sehen konnten,
+gibt es für jeden Polynomgrad $n$ ein Intervall $[a(n), a(n) + 1]$,
+$a(n) \in \mathbb{Z}$,
+in welchem der relative Fehler minimal ist.
+Die Funktionalgleichung der Gamma-Funktion \eqref{laguerre:gamma_funktional}
+könnte uns hier helfen,
+das Problem in den Griff zu bekommen.
+
+\subsubsection{Analyse des Integranden}
+Wie wir im vorherigen Abschnitt gesehen haben,
+scheint der Integrand problematisch.
+Darum möchten wir ihn jetzt analysieren,
+damit wir ihn besser verstehen können.
+Dies sollte es uns ermöglichen,
+anschliessend geeignete Gegenmassnahmen zu entwickeln.
+
+% Dieser Abschnitt soll eine grafisches Verständnis dafür schaffen,
+% wieso der Integrand so problematisch ist.
+% Was das heisst sollte in Abbildung~\ref{laguerre:fig:integrand} 
+% und Abbildung~\ref{laguerre:fig:integrand_exp} grafisch dargestellt werden.
+\begin{figure}
+\centering
+% \input{papers/laguerre/images/integrand.pgf}

+\caption{Integrand $x^z$ mit unterschiedlichen Werten für $z$}
+\label{laguerre:fig:integrand}
+\end{figure}
+
+In Abbildung~\ref{laguerre:fig:integrand} ist der Integrand $x^z$ für
+unterschiedliche Werte von $z$ dargestellt.
+Dies entspricht der zu integrierenden Funktion $f(x)$
+der Gauss-Laguerre-Quadratur für die Gamma-Funktion.
+Man erkennt,
+dass für kleine $z$ sich ein singulärer Integrand ergibt
+und auch für grosse $z$ wächst der Integrand sehr schnell an.
+Das heisst,
+die Ableitungen im Fehlerterm divergieren noch schneller
+und das wirkt sich negativ auf die Genauigkeit der Approximation aus.
+Somit lässt sich hier sagen,
+dass kleine Exponenten um $0$ genauere Resultate liefern sollten.
+
+\begin{figure}
+\centering
+% \input{papers/laguerre/images/integrand_exp.pgf}
+\includegraphics{papers/laguerre/images/integrand_exp.pdf}
+%\vspace{-12pt}
+\caption{Integrand $x^z e^{-x}$ mit unterschiedlichen Werten für $z$}
+\label{laguerre:fig:integrand_exp}
+\end{figure}
+
+In Abbildung~\ref{laguerre:fig:integrand_exp} fügen wir
+die Dämpfung der Gewichtsfunktion $w(x)$
+der Gauss-Laguerre-Quadratur wieder hinzu
+und erhalten so wieder den kompletten Integranden $x^{z} e^{-x}$
+der Gamma-Funktion.
+Für negative $z$ ergeben sich immer noch Singularitäten,
+wenn $x \rightarrow 0$.
+Um $x = 1$ wächst der Term $x^z$ für positive $z$
+schneller als die Dämpfung $e^{-x}$,
+aber für $x \rightarrow \infty$ geht der Integrand gegen $0$.
+Das führt zu glockenförmigen Kurven,
+die für grosse Exponenten $z$ nach der Stelle $x=1$ schnell anwachsen.
+Zu grosse Exponenten $z$ sind also immer noch problematisch.
+Kleine positive $z$ scheinen nun aber auch zulässig zu sein.
+Damit formulieren wir die Vermutung,
+dass $a(n)$,
+welches das Intervall $[a(n), a(n) + 1]$ definiert,
+in dem der relative Fehler minimal ist,
+grösser als $0$ und kleiner als $2n-1$ ist.
+
+\subsubsection{Ansatz mit Verschiebungsterm}
+% Mittels der Funktionalgleichung \eqref{laguerre:gamma_funktional} 
+% kann der Wert von $\Gamma(z)$ im Intervall $z \in [a,a+1]$,
+% in dem der relative Fehler minimal ist,
+% evaluiert werden und dann mit der Funktionalgleichung zurückverschoben werden.
 Nun stellt sich die Frage,
 ob die Approximation mittels Gauss-Laguerre-Quadratur verbessert werden kann,
-wenn man das Problem an einer geeigneten Stelle evaluiert und
-dann zurückverschiebt mit der Funktionalgleichung.
-Dazu wollen wir den Fehlerterm in
-Gleichung~\eqref{laguerre:lagurre:lag_error} anpassen und dann minimieren.
-Zunächst wollen wir dies nur für $z\in \mathbb{R}$ und $0<z<1$ definieren.
-Zudem nehmen wir an, dass die optimale Stelle $x^* \in \mathbb{R}$, $z < x^*$
-ist.
-Dann fügen wir einen Verschiebungsterm um $m$ Stellen ein, daraus folgt
+wenn man das Problem in einem geeigneten Intervall $[a(n), a(n)+1]$,
+$a(n) \in \mathbb{Z}$,
+evaluiert und dann mit der
+Funktionalgleichung \eqref{laguerre:gamma_funktional} zurückverschiebt.
+Für dieses Vorhaben führen wir einen Verschiebungsterm $m \in \mathbb{Z}$ ein.
+Passen wir \eqref{laguerre:naive_lag}
+mit dem Verschiebungsterm $m$
+%,der $z$ and die Stelle $z_m = z + m$ verschiebt, 
+an,
+ergibt sich
+\begin{align}
+\Gamma(z)

+\subsubsection{Finden der optimalen Berechnungsstelle}
+Um die optimale Stelle $z^*(n) \in \left[a(n), a(n) + 1\right]$,
+$z^*(n) \in \mathbb{R}$,
+zu finden,
+erweitern wir denn Fehlerterm \eqref{laguerre:gamma_err_simple}
+und erhalten
+\begin{align}
+R_{n,m}(\xi)
+=
+s(z, m) \cdot (z - 2n)_{2n} \frac{(n!)^2}{(2n)!} \xi^{z + m - 2n - 1}
+,\quad
+\text{für }
+\xi \in (0, \infty)
+\label{laguerre:gamma_err_shifted}
+.
+\end{align}
+%
+\begin{figure}
+\centering
+\includegraphics{papers/laguerre/images/targets.pdf}
+% %\vspace{-12pt}
+\caption{$m^*$ in Abhängigkeit von $z$ und $n$}
+\label{laguerre:fig:targets}
+\end{figure}
+%
+Daraus formulieren wir das Optimierungproblem
+\begin{align*}
+m^*
+=
+\operatorname*{argmin}_m \max_\xi R_{n,m}(\xi)
+.
+\end{align*}
+Allerdings ist die Funktion $R_{n,m}(\xi)$ unbeschränkt und
+hat die gleichen Probleme wie die Fehlerabschätzung des direkten Ansatzes.
+Dazu müssten wir $\xi$ versuchen,
+unter Kontrolle zu bringen,
+was ein äussersts schwieriges Unterfangen zu sein scheint.
+Da die Gauss-Quadratur aber sowieso
+nur wirklich praktisch sinnvoll für kleine $n$ ist,
+können die Intervalle $[a(n), a(n)+1]$ empirisch gesucht werden.
+
+Wir bestimmen nun die optimalen Verschiebungsterme empirisch
+für $n = 1,\ldots, 12$ im Intervall $z \in (0, 1)$,
+da $z$ sowieso mit den Term $m$ verschoben wird,
+reicht es,
+die $m^*$ nur in diesem Intervall zu analysieren.
+In Abbildung~\ref{laguerre:fig:targets} sind die empirisch bestimmten $m^*$
+abhängig von $z$ und $n$ dargestellt.
+In $n$-Richtung lässt sich eine klare lineare Abhängigkeit erkennen und
+die Beziehung zu $z$ ist negativ,
+d.h. wenn $z$ grösser ist, wird $m^*$ kleiner.
+Allerdings ist die genaue Beziehung zu $z$
+aus dieser Grafik nicht offensichtlich,
+aber sie scheint regelmässig zu sein.
+Es lässt die Vermutung aufkommen,
+dass die Restriktion von $m^* \in \mathbb{Z}$ Rundungsprobleme verursacht.
+Wir versuchen,
+dieses Problem via lineare Regression und geeignete Rundung zu beheben.
+Den linearen Regressor
+\begin{align*}
+\hat{m}
+=
+\alpha n + \beta
+\end{align*}
+machen wir nur abhängig von $n$,
+in dem wir den Mittelwert $\overline{m}$ von $m^*$ über $z$ berechnen.
+

+
+In Abbildung~\ref{laguerre:fig:schaetzung} sind die Resultate
+der linearen Regression aufgezeigt mit $\alpha = 1.34154$ und $\beta =
+0.848786$.
+Die lineare Beziehung ist ganz klar ersichtlich und der Fit scheint zu genügen.
+Der optimale Verschiebungsterm kann nun mit
+\begin{align*}
+m^*
+\approx
+\lceil \hat{m} - z \rceil
+=
+\lceil \alpha n + \beta - z \rceil
+\end{align*}
+% kann nun mit dem linearen Regressor und $z$
+gefunden werden.
+
+\subsubsection{Evaluation des Schätzers}
+In einem ersten Schritt möchten wir analysieren,
+wie gut die Abschätzung des optimalen Verschiebungsterms ist.
+Dazu bestimmen wir den relativen Fehler für verschiedene Verschiebungsterme $m$
+in der Nähe von $m^*$ bei gegebenem Polynomgrad $n = 8$ für $z \in (0, 1)$.
+In Abbildung~\ref{laguerre:fig:rel_error_shifted} sind die relativen Fehler
+der Approximation dargestellt.
+Man kann deutlich sehen,
+dass der relative Fehler anwächst,
+je weiter der Verschiebungsterm vom idealen Wert abweicht.
+Zudem scheint der Schätzer den optimalen Verschiebungsterm gut zu bestimmen,
+da der Schätzer zuerst der grünen Linie folgt und
+dann beim Übergang auf die orange Linie wechselt.

+$m^*$ bezeichnet hier den optimalen Verschiebungsterm.}
+\label{laguerre:fig:rel_error_shifted}
+\end{figure}
+
+\subsubsection{Resultate}
+Das Verfahren scheint für den Grad $n=8$ und $z \in (0,1)$ gut zu funktioneren.
+Es stellt sich nun die Frage,
+wie der relative Fehler sich für verschiedene $z$ und $n$ verhält.
+In Abbildung~\ref{laguerre:fig:rel_error_range} sind die relativen Fehler für
+unterschiedliche $n$ dargestellt.
+Der relative Fehler scheint immer noch Nullstellen aufzuweisen
+für ganzzahlige $z$.
+Durch das Verschieben ergibt sich jetzt aber,
+wie zu erwarten war,
+ein periodischer relativer Fehler mit einer Periodendauer von $1$.
+Zudem lässt sich erkennen,
+dass der Fehler abhängig von der Ordnung $n$
+des verwendeten Laguerre-Polynoms ist.
+Wenn der Grad $n$ um $1$ erhöht wird,
+verbessert sich die Genauigkeit des Resultats um etwa eine signifikante Stelle.
+
+In Abbildung~\ref{laguerre:fig:rel_error_complex}
+ist der Betrag des relativen Fehlers in der komplexen Ebene dargestellt.
+Je stärker der Imaginäranteil von $z$ von $0$ abweicht,
+umso schlechter wird die Genauigkeit der Approximation.
+Das erstaunt nicht weiter,
+da die Gauss-Quadratur eigentlich nur für reelle Zahlen definiert ist.
+Wenn der Imaginäranteil von $z$ ungefähr $0$ ist,
+lässt sich das gleiche Bild beobachten wie in
+Abbildung~\ref{laguerre:fig:rel_error_range}.

+\subsubsection{Vergleich mit Lanczos-Methode}
+Nun stellt sich die Frage,
+wie das in diesem Abschnitt beschriebene Approximationsverfahren
+der Gamma-Funktion sich gegenüber den üblichen Approximationsverfahren schlägt.
+Eine häufig verwendete Methode ist die Lanczos-Approximation,
+welche gegeben ist durch
+\begin{align}
+\Gamma(z + 1)
+\approx
+\sqrt{2\pi} \left( z + \sigma + \frac{1}{2} \right)^{z + 1/2}
+e^{-(z + \sigma + 1/2)} \sum_{k=0}^n g_k H_k(z)
+,
+\end{align}
+wobei
+\begin{align*}
+g_k = \frac{e^\sigma \varepsilon_k (-1)^k}{\sqrt{2\pi}}
+\sum_{r=0}^k (-1)^r \, \binom{k}{r} \, (k)_r
+\left( \frac{e}{r + \sigma + \frac{1}{2}}\right)^{r + 1/2}
+,
+\end{align*}
+\begin{align*}
+\varepsilon_k
+=
+\begin{cases}
+1 & \text{für } k = 0 \\
+2 & \text{sonst}
+\end{cases}
+\quad \text{und}\quad
+H_k(z)
+=
+\frac{(-1)^k (-z)_k}{(z+1)_k}
+\end{align*}
+mit $H_0 = 1$ und $\sum_0^n g_k = 1$ (siehe \cite{laguerre:lanczos}).
+Diese Methode wurde zum Beispiel in
+{\em GNU Scientific Library}, {\em Boost}, {\em CPython} und
+{\em musl} implementiert.
+Diese Methode erreicht für $n = 7$ typischerweise eine Genauigkeit von $13$
+korrekten, signifikanten Stellen für reelle Argumente.
+Zum Vergleich: die vorgestellte Methode erreicht für $n = 7$
+eine minimale Genauigkeit von $6$ korrekten, signifikanten Stellen
+für reelle Argumente.
 
-\subsection{Resultate}
+\subsubsection{Fazit}
+% Das Resultat ist etwas enttäuschend,
+Die Genauigkeit der vorgestellten Methode schneidet somit schlechter ab
+als die Lanczos-Methode.
+Dieser Erkenntnis kommt nicht ganz unerwartet,
+% aber nicht unerwartet,
+da die Lanczos-Methode spezifisch auf dieses Problem zugeschnitten ist und
+unsere Methode eine erweiterte allgemeine Methode ist.
+Allerdings besticht die vorgestellte Methode
+durch ihre stark reduzierte Komplexität. % und Rechenaufwand.
+% Was die Komplexität der Berechnungen im Betrieb angeht,
+% ist die Gauss-Laguerre-Quadratur wesentlich ressourcensparender,
+% weil sie nur aus $n$ Funktionsevaluationen,
+% wenigen Multiplikationen und Additionen besteht.
+Was den Rechenaufwand angeht,
+benötigt die vorgestellte Methode,
+für eine Genauigkeit von $n-1$ signifikanten Stellen,
+nur $n$ Funktionsevaluationen
+und wenige zusätzliche Multiplikationen und Additionen.
+Demzufolge könnte diese Methode Anwendung in Systemen mit wenig Rechenleistung
+und/oder knappen Energieressourcen finden.
+Die vorgestellte Methode ist ein weiteres Beispiel dafür,
+wie Verfahren durch die Kenntnis der Eigenschaften einer Funktion
+verbessert werden können.

-{\large \color{red} TODO: Einleitung}
+{\parindent0pt Die} Laguerre\--Polynome,
+benannt nach Edmond Laguerre (1834 -- 1886),
+sind Lösungen der ebenfalls nach %Laguerre 
+ihm
+benannten Differentialgleichung.
+Laguerre entdeckte diese Polynome, als er Approximations\-methoden
+für das Integral
+% $\int_0^\infty \exp(-x) / x \, dx $ 
+\begin{align*}
+\int_0^\infty \frac{e^{-x}}{x} \, dx
+\end{align*}
+suchte.
+Darum möchten wir uns in diesem Kapitel,
+ganz im Sinne des Entdeckers,
+den Laguerre-Polynomen für Approximationen von Integralen mit
+exponentiell abfallenden Funktionen widmen.
+Namentlich werden wir versuchen, mittels Laguerre-Polynomen und
+der Gauss-Quadratur eine geeignete Approximation für die Gamma-Funktion zu
+finden.
+
+Laguerre-Polynome tauchen zudem auch in der Quantenmechanik im radialen Anteil
+der Lösung für die Schrödinger-Gleichung eines Wasserstoffatoms auf.

- {\large \color{red} TODO: Einleitung und kurze Beschreibung Gauss-Quadratur}
+\rhead{Gauss-Quadratur}%
+Die Gauss-Quadratur ist ein numerisches Integrationsverfahren,
+welches die Eigenschaften von orthogonalen Polynomen verwendet.
+Herleitungen und Analysen der Gauss-Quadratur können im
+Abschnitt~\ref{buch:orthogonal:section:gauss-quadratur} gefunden werden.
+Als grundlegende Idee wird die Beobachtung,
+dass viele Funktionen sich gut mit Polynomen approximieren lassen,
+verwendet.
+Stellt man also sicher,
+dass ein Verfahren gut für Polynome funktioniert,
+sollte es auch für andere Funktionen angemessene Resultate liefern.
+Es wird ein Interpolationspolynom verwendet,
+welches an den Punkten $x_0 < x_1 < \ldots < x_n$
+die Funktionwerte~$f(x_i)$ annimmt.
+Als Resultat kann das Integral via einer gewichteten Summe der Form
 \begin{align}
-\int_a^b f(x) w(x)
+\int_a^b f(x) w(x) \, dx
 \approx
-\sum_{i=1}^N f(x_i) A_i
+\sum_{i=1}^n f(x_i) A_i
 \label{laguerre:gaussquadratur}
 \end{align}
+berechnet werden.
+Die Gauss-Quadratur ist exakt für Polynome mit Grad $2n -1$,
+wenn ein Interpolationspolynom von Grad $n$ gewählt wurde.
 
-\subsection{Gauss-Laguerre-Quadratur
+\subsection{Gauss-Laguerre-Quadratur%
 \label{laguerre:subsection:gausslag-quadratur}}
-Die Gauss-Quadratur kann auch auf Skalarprodukte mit Gewichtsfunktionen
-ausgeweitet werden.
-In unserem Falle möchten wir die Gauss Quadratur auf die Laguerre-Polynome
-$L_n$ ausweiten.
-Diese sind orthogonal im Intervall $(0, \infty)$ bezüglich
-der Gewichtsfunktion $e^{-x}$.
-Gleichung~\eqref{laguerre:laguerrequadratur} lässt sich wiefolgt umformulieren:
+Wir möchten nun die Gauss-Quadratur auf die Berechnung
+von uneigentlichen Integralen erweitern,
+spezifisch auf das Intervall~$(0, \infty)$.
+Mit dem vorher beschriebenen Verfahren ist dies nicht direkt möglich.
+% Mit einer Transformation
+% \begin{align*}
+% x
+% =
+% % a + 
+% \frac{1 - t}{t}
+% \end{align*}
+% die das unendliche Intervall~$(0, \infty)$ 
+% auf das Intervall~$[0, 1]$ transformiert,
+% kann dies behoben werden.
+% % Für unseren Fall gilt $a = 0$.
+Das Integral eines Polynomes in diesem Intervall ist immer divergent.
+Es ist also nötig,
+den Integranden durch Funktionen zu approximieren,
+die genügend schnell gegen $0$ gehen.
+Man kann Polynome beliebigen Grades verwenden,
+wenn sie mit einer Funktion multipliziert werden,
+die schneller gegen $0$ geht als jedes Polynom.
+Damit stellen wir sicher,
+dass das Integral immer noch konvergiert.
+% Darum müssen wir das Polynom mit einer Funktion multiplizieren,
+% die schneller als jedes Polynom gegen $0$ geht,
+% damit das Integral immer noch konvergiert.
+Die Laguerre-Polynome $L_n$ schaffen hier Abhilfe,
+da ihre Gewichtsfunktion $w(x) = e^{-x}$ schneller
+gegen $0$ konvergiert als jedes Polynom.
+% In unserem Falle möchten wir die Gauss Quadratur auf die Laguerre-Polynome
+% $L_n$ ausweiten.
+% Diese sind orthogonal im Intervall $(0, \infty)$ bezüglich
+% der Gewichtsfunktion $e^{-x}$.
+Um also das Integral einer Funktion $g(x)$ im Intervall~$(0,\infty)$ zu
+berechen,
+formt man das Integral wie folgt um:
+\begin{align*}
+\int_0^\infty g(x) \, dx
+=
+\int_0^\infty f(x) e^{-x} \, dx
+\end{align*}
+Wir approximieren dann $f(x)$ durch ein Interpolationspolynom
+wie bei der Gauss-Quadratur.
+% Die Gleichung~\eqref{laguerre:gaussquadratur} lässt sich daher wie folgt
+% umformulieren:
+Die Gleichung~\eqref{laguerre:gaussquadratur} wird also
+für die Gauss-Laguerre-Quadratur zu
 \begin{align}
 \int_{0}^{\infty} f(x) e^{-x} dx
 \approx
-\sum_{i=1}^{N} f(x_i) A_i
+\sum_{i=1}^{n} f(x_i) A_i
 \label{laguerre:laguerrequadratur}
+.
 \end{align}
 
 \subsubsection{Stützstellen und Gewichte}
 Nach der Definition der Gauss-Quadratur müssen als Stützstellen die Nullstellen
-des verwendeten Polynoms genommen werden.
-Das heisst für das Laguerre-Polynom $L_n$ müssen dessen Nullstellen $x_i$ und
-als Gewichte $A_i$ werden die Integrale $l_i(x)e^{-x}$ verwendet werden.
+des Approximationspolynoms genommen werden.
+Für das Laguerre-Polynom $L_n(x)$ müssen demnach dessen Nullstellen $x_i$ und
+als Gewichte $A_i$ die Integrale von $l_i(x) e^{-x}$ verwendet werden.
 Dabei sind
 \begin{align*}
 l_i(x_j)

 \begin{cases}
-1 & i=j           \\
-0 & \text{sonst.}
+1 & i=j          \\
+0 & \text{sonst}
 \end{cases}
+% .
 \end{align*}
-Laut \cite{abramowitz+stegun} sind die Gewichte also
-\begin{align}
+die Lagrangeschen Interpolationspolynome.
+Laut \cite{laguerre:hildebrand2013introduction} können die Gewichte mit
+\begin{align*}
+A_i
+ & =
+-\frac{C_{n+1} \gamma_n}{C_n \phi'_n(x_i) \phi_{n+1} (x_i)}
+\end{align*}
+berechnet werden.
+$C_i$ entspricht dabei dem Koeffizienten von $x^i$
+des orthogonalen Polynoms $\phi_n(x)$, $\forall i =0,\ldots,n$ und
+\begin{align*}
+\gamma_n
+=
+\int_0^\infty w(x) \phi_n^2(x)\,dx
+\end{align*}
+dem Normalisierungsfaktor.
+
+Wir setzen nun $\phi_n(x) = L_n(x)$ und
+nutzen den Vorzeichenwechsel der Laguerre-Koeffizienten
+(ersichtlich am Term $(-1)^k$ in \eqref{laguerre:polynom})
+aus,
+damit erhalten wir
+\begin{align*}
 A_i
+ & =
+-\frac{C_{n+1} \gamma_n}{C_n L'_n(x_i) L_{n+1} (x_i)}
+\\
+ & = \frac{C_n}{C_{n-1}} \frac{\gamma_{n-1}}{L_{n-1}(x_i) L'_n(x_i)}
+.
+\end{align*}
+Für Laguerre-Polynome gilt
+\begin{align*}
+\frac{C_n}{C_{n-1}}
 =
-\frac{x_i}{(n + 1)^2 \left[ L_{n + 1}(x_i)\right]^2}
+-\frac{1}{n}
+\quad \text{und} \quad
+\gamma_n
+=
+1
+.
+\end{align*}
+Daraus folgt
+\begin{align}
+A_i
+ & =
+- \frac{1}{n L_{n-1}(x_i) L'_n(x_i)}
+\label{laguerre:gewichte_lag_temp}
+.
+\end{align}
+Nun kann die Rekursionseigenschaft der Laguerre-Polynome
+\cite{laguerre:hildebrand2013introduction}
+% (siehe \cite{laguerre:hildebrand2013introduction})
+\begin{align*}
+x L'_n(x)
+ & =
+n L_n(x) - n L_{n-1}(x)
+\\
+ & = (x - n - 1) L_n(x) + (n + 1) L_{n+1}(x)
+\end{align*}
+umgeformt werden und da $x_i$ die Nullstellen von $L_n(x)$ sind,
+vereinfacht sich die Gleichung zu
+\begin{align*}
+x_i L'_n(x_i)
+ & =
+- n L_{n-1}(x_i)
+\\
+ & =
+(n + 1) L_{n+1}(x_i)
+.
+\end{align*}
+Setzen wir diese Beziehung nun in \eqref{laguerre:gewichte_lag_temp} ein,
+ergibt sich
+\begin{align}
+\nonumber
+A_i
+ & =
+\frac{1}{x_i \left[ L'_n(x_i) \right]^2}
+\\
+ & =
+\frac{x_i}{(n+1)^2 \left[ L_{n+1}(x_i) \right]^2}
 .
 \label{laguerre:quadratur_gewichte}
 \end{align}
 
 \subsubsection{Fehlerterm}
+Die Gauss-Laguerre-Quadratur mit $n$ Stützstellen berechnet Integrale
+von Polynomen bis zum Grad $2n - 1$ exakt.
+Für beliebige Funktionen kann eine Fehlerabschätzung angegeben werden.
 Der Fehlerterm $R_n$ folgt direkt aus der Approximation
 \begin{align*}
-\int_0^{\infty} f(x) e^{-x} dx
+\int_0^{\infty} f(x) e^{-x} \, dx
 =
 \sum_{i=1}^n f(x_i) A_i + R_n
 \end{align*}
-un \cite{abramowitz+stegun} gibt in als
+und \cite{laguerre:abramowitz+stegun} gibt ihn als
 \begin{align}
 R_n
-=
+ & =
+\frac{f^{(2n)}(\xi)}{(2n)!} \int_0^\infty l(x)^2 e^{-x}\,dx
+\\
+ & =
 \frac{(n!)^2}{(2n)!} f^{(2n)}(\xi)
 ,\quad
 0 < \xi < \infty

 \end{align}
 an.

-Noch mehr Text / bessere Beschreibungen in allen Abschnitten

+Der Fehler ist also abhängig von der $2n$-ten Ableitung
+der zu integrierenden Funktion.

+\section{Was sind Verfolgungskurven?
+\label{lambertw:section:Was_sind_Verfolgungskurven}}
+\rhead{Was sind Verfolgungskurven?}
+
+Verfolgungskurven tauchen oft auf bei Fragen wie welchen Pfad begeht ein Hund während er einer Katze nachrennt.
+Ein solches Problem hat im Kern immer ein Verfolger und sein Ziel.
+Der Verfolger verfolgt sein Ziel, das versucht zu entkommen.
+Der Pfad, der der Verfolger während der Verfolgung begeht, wird Verfolgungskurve genannt.
+Um diese Kurve zu bestimmen, kann das Verfolgungsproblem als Differentialgleichung formuliert werden.
+Diese Differentialgleichung entspringt der Verfolgungsstrategie des Verfolgers.
+
+
+\subsection{Verfolger und Verfolgungsstrategie
+\label{lambertw:subsection:Verfolger}}
+Wie bereits erwähnt, wird der Verfolger durch seine Verfolgungsstrategie definiert.
+Wir nehmen an, dass sich der Verfolger stur an eine Verfolgungsstrategie hält.
+Dabei gibt es viele mögliche Strategien, die der Verfolger wählen könnte.
+Die möglichen Strategien entstehen durch Festlegung einzelner Parameter, die der Verfolger kontrollieren kann.
+Der Verfolger hat nur einen direkten Einfluss auf seinen Geschwindigkeitsvektor.
+Mit diesem kann er neben Richtung und Betrag auch den Abstand zwischen Verfolger und Ziel kontrollieren.
+Wenn zwei dieser drei Parameter durch die Strategie definiert werden, ist der dritte nicht mehr frei.
+Daraus folgt, dass eine Strategie zwei dieser drei Parameter festlegen muss, um den Verfolger komplett zu beschreiben.
+

+        \hline
+        \text{}&\text{Geschwindigkeit}&\text{Abstand}&\text{Richtung}\\

+        
+        \text{Strategie 3}
+        & \text{konstant} & \text{-} & \text{etwas voraus Zielen}\\
+        \hline
+    \end{tabular}
+    \caption{mögliche Verfolgungsstrategien}
+    \label{lambertw:table:Strategien}
+\end{table}
+
+\begin{figure}
+    \centering
+	\includegraphics[scale=0.1]{./papers/lambertw/Bilder/pursuerDGL2.pdf}
+    \caption{Vektordarstellung Strategie 1}
+    \label{lambertw:grafic:pursuerDGL2}
+\end{figure}
+
+In der Tabelle \eqref{lambertw:table:Strategien} sind drei mögliche Strategien aufgezählt.
+Im Folgenden wird nur noch auf die Strategie 1 eingegangen.
+Bei dieser Strategie ist die Geschwindigkeit konstant und der Verfolger bewegt sich immer direkt auf sein Ziel zu.
+In der Abbildung \eqref{lambertw:grafic:pursuerDGL2} ist das Problem dargestellt,
+wobei $\vec{V}$ der Ortsvektor des Verfolgers, $\vec{Z}$ der Ortsvektor des Ziels und $\dot{\vec{V}}$ der Geschwindigkeitsvektor des Verfolgers ist.
+Die konstante Geschwindigkeit kann man mit der Gleichung
+\begin{equation}
+    |\dot{\vec{V}}|
+    = \operatorname{const} = A
+    \quad A\in\mathbb{R}>0
+\end{equation}
+darstellen. Der Geschwindigkeitsvektor wiederum kann mit der Gleichung
+\begin{equation}
+    \frac{\vec{Z}-\vec{V}}{|\vec{Z}-\vec{V}|}\cdot|\dot{\vec{V}}|
+    =
+    \dot{\vec{V}}
+\end{equation}
+beschrieben werden.
+Die Differenz der Ortsvektoren $\vec{V}$ und $\vec{Z}$ ist ein Vektor der vom Punkt $V$ auf $Z$ zeigt.
+Da die Länge dieses Vektors beliebig sein kann, wird durch Division durch den Betrag, die Länge auf eins festgelegt.
+Aus dem Verfolgungsproblem ist auch ersichtlich, dass die Punkte $V$ und $Z$ nicht am gleichen Ort starten und so eine Division durch Null ausgeschlossen ist.
+Wenn die Punkte $V$ und $Z$ trotzdem am gleichen Ort starten, ist die Lösung trivial.
+Nun wird die Gleichung mit $\dot{\vec{V}}$ skalar multipliziert, um das Gleichungssystem von zwei auf eine Gleichung zu reduzieren. Somit ergeben sich
+\begin{align}
+    \frac{\vec{Z}-\vec{V}}{|\vec{Z}-\vec{V}|}\cdot|\dot{\vec{V}}|\cdot\dot{\vec{V}}
+    &=
+    |\dot{\vec{V}}|^2
+    \\
+    \label{lambertw:pursuerDGL}
+    \frac{\vec{Z}-\vec{V}}{|\vec{Z}-\vec{V}|}\cdot \frac{\dot{\vec{V}}}{|\dot{\vec{V}}|}
+    &=
+    1 \text{.}
+\end{align}
+Die Lösungen dieser Differentialgleichung sind die gesuchten Verfolgungskurven, insofern der Verfolger die Strategie 1 verwendet.
+
+\subsection{Ziel
+\label{lambertw:subsection:Ziel}}
+Als nächstes gehen wir auf das Ziel ein.
+Wie der Verfolger wird auch unser Ziel sich strikt an eine Fluchtstrategie halten, welche von Anfang an bekannt ist.
+Diese Strategie kann als Parameterdarstellung der Position nach der Zeit beschrieben werden.
+Zum Beispiel könnte ein Ziel auf einer Geraden flüchten, welches auf einer Ebene mit der Parametrisierung
+
+\begin{equation}
+    \vec{Z}(t)
+    =
+    \left( \begin{array}{c} 0 \\  t \end{array} \right)
+\end{equation}
+
+beschrieben werden könnte.
+Mit dieser Gleichung ist das Ziel auch schon vollumfänglich definiert.
+Die Fluchtkurve kann eine beliebige Form haben, jedoch wird die zu lösende Differentialgleichung für die Verfolgungskurve immer komplexer.
+

+\rhead{Wird das Ziel erreicht?}
+
+Sehr oft kommt es vor, dass bei Verfolgungsproblemen die Frage auftaucht, ob das Ziel überhaupt erreicht wird.
+Wenn zum Beispiel die Geschwindigkeit des Verfolgers kleiner ist als diejenige des Ziels, gibt es Anfangsbedingungen bei denen das Ziel nie erreicht wird.
+Im Anschluss dieser Frage stellt sich meist die nächste Frage, wie lange es dauert bis das Ziel erreicht wird.
+Diese beiden Fragen werden in diesem Kapitel behandelt und an einem Beispiel betrachtet.
+%
+%\subsection{Ziel erreichen (überarbeiten)
+%\label{lambertw:subsection:ZielErreichen}}
+Für diese Betrachtung wird das Beispiel aus \eqref{lambertw:section:teil4} zur Hilfe genommen.
+Wir verwenden die hergeleiteten Gleichungen \eqref{lambertw:eqFunkXNachT} für Startbedingung im ersten Quadranten
+\begin{align*}
+    x\left(t\right)
+    &=
+    x_0\cdot\sqrt{\frac{W\left(\chi\cdot e^{\chi-\frac{4t}{r_0-y_0}}\right)}{\chi}} \\
+    y(t)
+    &=
+    \frac{1}{4}\left(\left(y_0+r_0\right)\left(\frac{x(t)}{x_0}\right)^2+\left(r_0-y_0\right)\operatorname{ln}\left(\left(\frac{x(t)}{x_0}\right)^2\right)-r_0+3y_0\right)\\
+    \chi
+    &=
+    \frac{r_0+y_0}{r_0-y_0}\\
+    \eta
+    &=
+    \left(\frac{x}{x_0}\right)^2\\
+    r_0
+    &=
+    \sqrt{x_0^2+y_0^2} \text{.}\\
+\end{align*}
+%
+Das Ziel wird erreicht, wenn die Koordinaten des Verfolgers mit denen des Ziels bei einem diskreten Zeitpunkt $t_1$ übereinstimmen.
+Somit gilt es
+
+\begin{equation*}
+    \vec{Z}(t_1)=\vec{V}(t_1)
+\end{equation*}
+%
+zu lösen.
+Aus dem vorangegangenem Beispiel, ist die Parametrisierung des Verfolgers und des Ziels bekannt.
+Das Ziel wird parametrisiert durch
+
+\begin{equation}
+    \vec{Z}(t)
+    =
+    \left( \begin{array}{c} 0 \\ t \end{array} \right)
+\end{equation}
+%
+und der Verfolger durch
+
+\begin{equation}
+    \vec{V}(t)
+    =
+    \left( \begin{array}{c} x(t) \\ y(t) \end{array} \right)
+    \text{.}
+\end{equation}
+%
+ Da $y(t)$ viel komplexer ist als $x(t)$ wird das Problem in zwei einzelne Teilprobleme zerlegt. Wobei die Bedingung der x- und y-Koordinaten einzeln überprüft werden. Es entstehen daher folgende Bedingungen
+
+\begin{align*}
+    0
+    &=
+    x(t)
+    =
+    x_0\sqrt{\frac{W\left(\chi\cdot e^{\chi-\frac{4t}{r_0-y_0}}\right)}{\chi}}
+    \\
+    t
+    &=
+    y(t)
+    =
+    \frac{1}{4}\left(\left(y_0+r_0\right)\left(\frac{x(t)}{x_0}\right)^2+\left(r_0-y_0\right)\operatorname{ln}\left(\left(\frac{x(t)}{x_0}\right)^2\right)-r_0+3y_0\right)
+    \\
+\end{align*}
+%
+, welche Beide gleichzeitig erfüllt sein müssen, damit das Ziel erreicht wurde.
+Zuerst wird die Bedingung der x-Koordinate betrachtet.
+Diese kann durch dividieren durch $x_0$, anschliessendes quadrieren und multiplizieren von $\chi$ vereinfacht werden. Daraus folgt 
+\begin{equation}
+	0
+	=
+	W\left(\chi\cdot e^{\chi-\frac{4t}{r_0-y_0}}\right)
+	\text{.}
+\end{equation}
+%
+Es ist zu beachten, dass $W(x)$ die Lambert W-Funktion ist, welche im Kapitel  \eqref{buch:section:lambertw} behandelt wurde.
+Diese Gleichung entspricht genau den Nullstellen der Lambert W-Funktion. Da die Lambert W-Funktion genau eine Nullstelle bei
+
+\begin{equation*}
+    W(0)=0
+\end{equation*}
+%
+besitzt, kann die Bedingung weiter vereinfacht werden zu
+
+\begin{equation}
+    0
+    =
+    \chi\cdot e^{\chi-\frac{4t}{r_0-y_0}}
+    \text{.}
+\end{equation}
+%
+Da $\chi\neq0$ und die Exponentialfunktion nie null sein kann, ist diese Bedingung unmöglich zu erfüllen.
+Beim Grenzwert für $t\rightarrow\infty$ geht die Exponentialfunktion gegen null.
+Dies nützt nicht viel, da unendlich viel Zeit vergehen müsste damit ein Einholen möglich wäre.
+Somit kann nach den Gestellten Bedingungen das Ziel nie erreicht werden.
+Aus der Symmetrie des Problems an der y-Achse können auch alle Anfangspunkte im zweiten Quadranten die Bedingungen nicht erfüllen.
+Bei allen Anfangspunkten mit $y_0<0$ ist ein Einholen unmöglich, da die Geschwindigkeit des Verfolgers und Ziels übereinstimmen und der Verfolger dem Ziel bereits am Anfang nachgeht.
+Wenn die Wertemenge der Anfangsbedingung um die positive y-Achse erweitert wird, kann das Ziel wiederum erreicht werden.
+Sobald der Verfolger auf der positiven y-Achse startet, bewegen sich Verfolger und Ziel aufeinander zu, da der Geschwindigkeitsvektor des Verfolgers auf das Ziel zeigt und der Verfolger sich auf der Fluchtgeraden befindet.
+Dies führt zwingend dazu, dass der Verfolger das Ziel erreichen wird.
+Die Verfolgungskurve kann in diesem Fall mit
+
+\begin{equation}
+    \vec{V}(t)
+    =
+    \left( \begin{array}{c} 0 \\ y_0-t \end{array} \right)
+\end{equation}
+%
+parametrisiert werden.
+Nun kann der Abstand zwischen Verfolger und Ziel leicht bestimmt und nach 0 aufgelöst werden.
+Daraus folgt
+
+\begin{equation}
+    0
+    =
+    |\vec{V}(t_1)-\vec{Z}(t_1)|
+    =
+    y_0-2t_1
+\end{equation}
+%
+, was aufgelöst zu
+
+\begin{equation}
+    t_1
+    =
+    \frac{y_0}{2}
+\end{equation}
+%
+führt.
+Nun ist klar, dass lediglich Anfangspunkte auf der positiven y-Achse oder direkt auf dem Ziel dazu führen, dass der Verfolger das Ziel bei $t_1$ einholt.
+Bei allen anderen Anfangspunkten wird der Verfolger das Ziel nie erreichen.
+Dieses Resultat ist aber eher akademischer Natur, weil der Verfolger und das Ziel als Punkt betrachtet wurden.
+Wobei aber in Realität nicht von Punkten sondern von Objekten mit einer räumlichen Ausdehnung gesprochen werden kann.
+Somit wird in einer nächsten Betrachtung untersucht, ob der Verfolger dem Ziel näher kommt als ein definierter Trefferradius.
+Falls dies stattfinden sollte, wird dies als Treffer interpretiert.
+Mathematisch kann dies mit
+
+\begin{equation}
+    |\vec{V}-\vec{Z}|<a_{min} \quad a_{min}\in\mathbb{R}>0
+\end{equation}
+%
+beschrieben werden, wobei $a_{min}$ dem Trefferradius entspricht.
+Durch quadrieren verschwindet die Wurzel des Betrages, womit
+
+\begin{equation}
+    |\vec{V}-\vec{Z}|^2<a_{min}^2 \quad a_{min}\in \mathbb{R} > 0
+\end{equation}

+Das zu verfolgende Ziel \(\vec{Z}\) bewegt sich entlang der \(y\)-Achse mit konstanter Geschwindigkeit \(v = 1\), beginnend beim Ursprung des Kartesischen Koordinatensystems. Der Verfolger \(\vec{V}\) startet auf einem beliebigen Punkt im ersten Quadranten und bewegt sich auch mit konstanter Geschwindigkeit \(|\dot{V}| = 1\) in Richtung Ziel. Diese Anfangspunkte oder Anfangsbedingungen können wie folgt formuliert werden:
+\begin{equation}
+	\vec{Z}
+	=
+	\left( \begin{array}{c} 0 \\ v \cdot t \end{array} \right)
+	=
+	\left( \begin{array}{c} 0 \\ t \end{array} \right)
+	,\:
+	\vec{V}
+	=
+	\left( \begin{array}{c} x \\ y \end{array} \right)
+	\:\text{und}\:\:
+	\bigl| \dot{V} \bigl|
+	=
+	1.
+	\label{lambertw:Anfangsbed}
+\end{equation}
+Wir haben nun die Anfangsbedingungen definiert, jetzt fehlt nur noch eine DGL, welche die fortlaufende Änderung der Position und Bewegungsrichtung des Verfolgers beschreibt. 
+Diese DGL haben wir bereits in Kapitel \ref{lambertw:subsection:Verfolger} definiert, und zwar Gleichung \eqref{lambertw:pursuerDGL}. Wenn man die Startpunkte einfügt ergibt sich folgender Ausdruck:
+\begin{equation}
+	\frac{\left( \begin{array}{c} 0-x \\ t-y \end{array} \right)}{\sqrt{x^2 + (t-y)^2}}
+	\cdot
+	\left(\begin{array}{c} \dot{x} \\ \dot{y} \end{array}\right)
+	=
+	1.
+	\label{lambertw:eqMitAnfangsbed}
+\end{equation}
+
+\subsection{DGL vereinfachen
+	\label{lambertw:subsection:DGLvereinfach}}
+Nun haben wir eine Gleichung, es stellt sich aber die Frage ob es überhaupt eine geschlossene Lösung dafür gibt. Eine Funktion welche die Beziehung \(y(x)\) beschreibt oder sogar \(x(t)\) und \(y(t)\) liefert. Zum jetzigen Zeitpunkt mag es nicht trivial scheinen, aber mit den gewählten Anfangsbedingungen \eqref{lambertw:Anfangsbed} ist es möglich eine geschlossene Lösung für die Gleichung \eqref{lambertw:eqMitAnfangsbed} zu finden.
+Auf dem Weg dahin muss die definierte DGL zuerst wesentlich vereinfacht werden, sei es mittels algebraische Umformungen oder mit den Tools aus der Analysis. Also legen wir los! 
+
+Zuerst müssen wir den Bruch in \eqref{lambertw:eqMitAnfangsbed} los werden, der sieht so nicht handlich aus. Dafür multiplizieren wir beidseitig mit dem Nenner:
+\begin{equation}
+	\left( \begin{array}{c} 0-x \\ t-y \end{array} \right)
+	\cdot
+	\left(\begin{array}{c} \dot{x} \\ \dot{y} \end{array}\right)
+	= \sqrt{x^2 + (t-y)^2}.
+	\label{lambertw:eqOhneBruch}
+\end{equation}
+In einem weiteren Schritt, lösen wir das Skalarprodukt auf und erhalten folgende Gleichung \eqref{lambertw:eqOhneSkalarprod} ohne vektorielle Grössen:
+\begin{equation}
+		-x \cdot \dot{x} + (t-y) \cdot \dot{y}
+		= \sqrt{x^2 + (t-y)^2}.
+		\label{lambertw:eqOhneSkalarprod}
+\end{equation}
+Im letzten Schritt, fällt die Nützlichkeit des Skalarproduktes in der Verfolgungsgleichung \eqref{lambertw:pursuerDGL} markant auf. Meiner Meinung ziemlich elegant und nicht selbstverständlich in der Lage zu sein, das Problem auf eine einzige Gleichung reduzieren zu können.
+
+Die nächsten Schritte sind sehr algebralastig und würden das lesen dieses Papers einfach nur mühsam machen, also werde ich diese auslassen. Hingegen werden ich die algebraische Hauptschritte erwähnen, die notwendig wären falls man es trotzdem selber ausprobieren möchte:
+\begin{itemize}
+	\item
+	Quadrieren und erweitern.
+	\item
+	Gruppieren.
+	\item
+	Substitution von einzelnen Thermen mittels der Beziehung \(\dot{x}^2 + \dot{y}^2 = 1\).
+	\item
+	Und das erkennen des Musters einer Binomischen Formel.
+\end{itemize} 
+Das Resultat aller dieser Vereinfachungen führen zu folgender Gleichung \eqref{lambertw:eqAlgVerinfacht}, die viel handhabbarer ist als zuvor:
+\begin{equation}
+	(x \dot{y} + (t-y) \dot{x})^2
+	= 0.
+	\label{lambertw:eqAlgVerinfacht}
+\end{equation}
+Da der linke Term gleich Null ist, muss auch der Inhalt des Quadrates gleich Null sein, somit folgt eine weitere Vereinfachung, welche zu einer im Vergleich zu \eqref{lambertw:eqOhneSkalarprod} wesentlich einfachere DGL führt:
+\begin{equation}
+	x \dot{y} + (t-y) \dot{x}
+	= 0.
+	\label{lambertw:eqGanzVerinfacht}
+\end{equation}
+Kompakt, ohne Wurzelterme und Quadrate, nur elementare Operationen und Ableitungen. Nun stellt sich die Frage wie es weiter gehen soll, bei der Gleichung \eqref{lambertw:eqGanzVerinfacht} scheinen keine weiteren Vereinfachungen möglich zu sein. Wir brauchen einen neuen Ansatz um unser Ziel einer möglichen Lösung zu verfolgen.
+
+\subsection{Zeitabhängigkeit loswerden
+	\label{lambertw:subsection:ZeitabhLoswerden}}
+Der nächste logischer Schritt schient irgendwie die Zeitabhängigkeit in der Gleichung \eqref{lambertw:eqGanzVerinfacht} loszuwerden, aber wieso? Nun, wie am Anfang von Abschnitt \ref{lambertw:subsection:DGLvereinfach} beschrieben, suchen wir eine Lösung der Art \(y(x)\), dies ist natürlich erst möglich wenn wir die Abhängigkeit nach \(t\) eliminieren können.
+
+Der erste Schritt auf dem Weg dahin, ist es die zeitlichen Ableitung los zu werden, dafür wird \eqref{lambertw:eqGanzVerinfacht} beidseitig mit \(\dot{x}\) dividiert, was erlaubt ist, weil diese Änderung ungleich Null ist:
+\begin{equation}
+	x \frac{\dot{y}}{\dot{x}} + (t-y) \frac{\dot{x}}{\dot{x}}
+	= 0.
+	\label{lambertw:eqVorKeineZeitAbleit}
+\end{equation}
+Der Grund dafür ist, dass
+\begin{equation}
+	\frac{\displaystyle\dot{y}}{\displaystyle\dot{x}} 
+	= \frac{\displaystyle\frac{dy}{dt}}{\displaystyle\frac{dx}{dt}}  
+	= \frac{dy}{dx}
+	= y^{\prime},
+	\label{lambertw:eqQuotZeitAbleit}
+\end{equation}
+und somit kann der Quotient dieser zeitlichen Ableitungen in eine Ableitung nach \(x\) umgewandelt werden.
+Nach dem diese Eigenschaft \eqref{lambertw:eqQuotZeitAbleit} in \eqref{lambertw:eqVorKeineZeitAbleit} eingesetzt wird und vereinfacht wurde, entsteht folgende neue Gleichung:
+\begin{equation}
+	x y^{\prime} + t - y
+	= 0.
+	\label{lambertw:DGLmitT}
+\end{equation}
+Hier wäre es natürlich passend wenn man die Abhängigkeit nach \(t\) komplett wegbringen könnte. Um dies zu erreichen muss man auf die Definition der Bogenlänge aus der Analysis zurückgreifen, wobei die Strecke \(s\) folgendem entspricht:
+\begin{equation}
+	s
+	= 
+	v \cdot t
+	=
+	1 \cdot t
+	=
+	t
+	=
+	\int_{\displaystyle x_0}^{\displaystyle x_{\text{end}}}\sqrt{1+y^{\prime\, 2}} \: dx.
+	\label{lambertw:eqZuBogenlaenge}
+\end{equation}
+Nicht gerade auffällig ist die Richtung in welche hier integriert wird. Wenn der Verfolger sich wie vorgesehen am Anfang im ersten Quadranten befindet, dann muss sich dieser nach links bewegen, was nicht der üblichen Integrationsrichtung entspricht. Um eine Integration wie üblich von links nach rechts ausführen zu können, müssen die Integrationsgenerzen vertauscht werden, was in einem Vorzeichenwechsel resultiert. Wenn man nun \eqref{lambertw:eqZuBogenlaenge} in die DGL \eqref{lambertw:DGLmitT} einfügt, dann ergibt sich folgender Ausdruck:
+\begin{equation}
+	x y^{\prime} - \int\sqrt{1+y^{\prime\, 2}} \: dx - y
+	= 0.
+	\label{lambertw:DGLohneT}
+\end{equation}
+Um das Integral los zu werden, leitet man den vorherigen Ausdruck \eqref{lambertw:DGLohneT} nach \(x\) ab und erhaltet folgende DGL \eqref{lambertw:DGLohneInt}:
+\begin{align}
+	y^{\prime}+ xy^{\prime\prime} - \sqrt{1+y^{\prime\, 2}} - y^{\prime}
+	&= 0, \\
+	xy^{\prime\prime} - \sqrt{1+y^{\prime\, 2}}
+	&= 0.
+	\label{lambertw:DGLohneInt}
+\end{align}
+Nun sind wir unserem Ziel einen weiteren Schritt näher. Die Gleichung \eqref{lambertw:DGLohneInt} mag auf den ersten Blick nicht gerade einfach sein, aber im Nächsten Abschnitt werden wir sehen, dass sie relativ einfach zu lösen ist.
+
+\subsection{DGL lösen
+	\label{lambertw:subsection:DGLloes}}
+Die Gleichung \eqref{lambertw:DGLohneInt} ist eine DGL zweiter Ordnung und kann 
+mittels der Substitution \(y^{\prime} = u\) in eine DGL erster Ordnung umgewandelt werden:
+\begin{equation}
+	xu^{\prime} - \sqrt{1+u^2}
+	= 0.
+	\label{lambertw:DGLmitU}
+\end{equation}
+Diese \eqref{lambertw:DGLmitU} zu lösen ist ziemlich einfach da sie separierbar ist, aus diesem Grund werde ich direkt zur Lösung \eqref{lambertw:loesDGLmitU} übergehen:
+\begin{align}
+	\operatorname{arsinh}(u)
+	&=
+	\operatorname{ln}(x) + C, \\
+	u
+	&=
+	\operatorname{sinh}(\operatorname{ln}(x) + C).
+	\label{lambertw:loesDGLmitU}
+\end{align}
+Indem man die Substitution rückgängig macht, erhält man eine weitere DGL erster Ordnung die bereits separiert ist und erhält folgende Gleichung:
+\begin{equation}
+	y^{\prime}
+	=
+	\operatorname{sinh}(\operatorname{ln}(x) + C).
+	\label{lambertw:loesDGLmitY}
+\end{equation}
+Diese \eqref{lambertw:loesDGLmitY} kann mit den selben Methoden gelöst werden wie \eqref{lambertw:DGLmitU}, diesmal aber in Kombination mit der exponentiellen Definition der \(\operatorname{sinh}\)-Funktion:
+\begin{equation}
+	y
+	=
+	C_1 + C_2 x^2 - \frac{\operatorname{ln}(x)}{8 \cdot C_2}.
+\end{equation}
+Nun haben wir eine Lösung, aber wie es immer mit Lösungen ist, stellt sich die Frage ob sie überhaupt plausibel ist. Dieser Frage werden wir in nächsten Abschnitt \ref{lambertw:subsection:LoesAnalys} nachgehen.
+
+\subsection{Lösung analysieren
+	\label{lambertw:subsection:LoesAnalys}}
+
+\begin{figure}
+	\centering
+	\includegraphics{papers/lambertw/Bilder/VerfolgungskurveBsp.png}
+	\caption[Graph der Verfolgungskurve]{Graph der Verfolgungskurve wobei, ({\color{red}rot}) die Funktion \ensuremath{y(x)} ist, ({\color{darkgreen}grün}) der quadratische Teil und ({\color{blue}blau}) dem \ensuremath{ln(x)}-Teil entspricht.
+	\label{lambertw:BildFunkLoes}
+	}
+\end{figure}
+
+Das Resultat, wie ersichtlich, ist folgende Funktion \eqref{lambertw:funkLoes} welche mittels Anfangsbedingungen parametrisiert werden kann: 
+\begin{equation}
+	{\color{red}{y(x)}}
+	=
+	C_1 + C_2 {\color{darkgreen}{x^2}} {\color{blue}{-}} \frac{\color{blue}{\operatorname{ln}(x)}}{8 \cdot C_2}.
+	\label{lambertw:funkLoes}
+\end{equation}
+Für die Koeffizienten \(C_1\) und \(C_2\) ergibt sich ein Anfangswertproblem, welches für deren Bestimmung gelöst werden muss. Zuerst soll aber eine qualitative Intuition, oder Idee für das Aussehen der Funktion \(y(x)\) geschaffen werden:
+\begin{itemize}
+	\item
+	Für grosse \(x\)-Werte, welche in der Regel in der Nähe von \(x_0\) sein sollten, ist der quadratisch Term in der Funktion \eqref{lambertw:funkLoes} dominant. 
+	\item
+	Für immer kleiner werdende \(x\) geht der Verfolger in Richtung \(y\)-Achse, wobei seine Steigung stetig sinkt, was Sinn macht wenn der Verfolgte entlang der \(y\)-Achse steigt. Irgendwann werden Verfolger und Ziel auf gleicher Höhe sein.
+	\item
+	Für \(x\)-Werte in der Nähe von \(0\) ist das asymptotische Verhalten des Logarithmus dominant, dies macht auch Sinn da sich der Verfolgte auf der \(y\)-Achse bewegt und der Verfolger im nachgeht.
+	\item
+	Aufgrund des Monotoniewechsels in der Kurve \eqref{lambertw:funkLoes} muss diese auch ein Minimum aufweisen. Es stellt sich nun die Frage: Wo befindet sich dieser Punkt? 
+	
+	Eine Abschätzung darüber kann getroffen werden und zwar, dass dieser dann entsteht, wenn \(A\) und \(P\) die gleiche \(y\)-Koordinaten besitzen. In diesem Moment ändert die Richtung der \(y\)-Komponente der Geschwindigkeit des Verfolgers, somit auch sein Vorzeichen und dadurch entsteht auch das Minimum.
+\end{itemize}
+Alle diese Eigenschafte stimmen mit dem überein, was man von einer Kurve dieser Art erwarten würde, welche durch die Grafik \ref{lambertw:BildFunkLoes} repräsentiert wurde. Nun stellt sich die Frage wie die Kurve wirklich aussieht. Dies wird im folgenden Abschnitt \ref{lambertw:subsection:AllgLoes} behandelt.
+
+\subsection{Anfangswertproblem 
+	\label{lambertw:subsection:AllgLoes}}
+Wie üblich bei der Suche nach einer exakten Lösung, kommt ein Anfangswertproblem vor. Um dieses zu lösen, müssen wir zuerst die Anfangswerte definieren. Da wir das Problem allgemein lösen wollen, ergeben sich folgende zwei Anfangswerte:
+\begin{equation}
+	y(x)\big \vert_{t=0}
+	=
+	y(x_0)
+	= 
+	y_0
+	\label{lambertw:eq1Anfangswert}
+\end{equation}
+und
+\begin{equation}
+	\frac{dy}{dx}\bigg \vert_{t=0}
+	=
+	y^{\prime}(x_0)
+	=
+	\frac{y_0}{x_0}.
+	\label{lambertw:eq2Anfangswert}
+\end{equation}
+Der zweite Anfangswert \eqref{lambertw:eq2Anfangswert} mag nicht grade offensichtlich sein. Die Erklärung dafür ist aber simpel: Der Verfolger wird sich zum Zeitpunkt \(t=0\) in Richtung Koordinatenursprung bewegen wollen, wo sich das Ziel befindet. Somit entsteht das Steigungsdreieck mit \(\Delta x = x_0\) und \(\Delta y = y_0\).
+
+Das Lösen des Anfangswertproblems ist ein Problem aus der Algebra, auf welches ich nicht unbedingt eingehen möchte. Zur Vollständigkeit und Nachvollziehbarkeit, werde ich aber das Gleichungssystem \eqref{lambertw:eqGleichungssystem} präsentieren, welches notwendig ist um das Anfangswertproblem zu lösen, sowie auch die allgemeine Lösung \eqref{lambertw:eqAllgLoes} die sich nach dem einsetzen der Koeffizienten \(C_1\) und \(C_2\) in die Funktion \eqref{lambertw:funkLoes} ergibt.
+
+\begin{itemize}
+	\item
+	Gleichungssystem:
+	\begin{subequations}
+		\begin{align}
+			y_0
+			&=
+			C_1 + C_2 x^2_0 - \frac{\operatorname{ln}(x_0)}{8 \cdot C_2}, \\
+			\frac{y_0}{x_0}
+			&=
+			2 \cdot  C_2 x_0 - \frac{1}{8 \cdot C_2 \cdot x_0}.
+		\end{align}
+		\label{lambertw:eqGleichungssystem}
+	\end{subequations}
+	\item
+	Die allgemeine Funktion:
+	\begin{equation}
+		y(x)
+		=
+		\frac{1}{4}\left(\left(y_0+r_0\right)\eta+\left(r_0-y_0\right)\operatorname{ln}\left(\eta\right)-r_0+3y_0\right)
+		\label{lambertw:eqAllgLoes}
+	\end{equation}
+	Damit die Funkion \eqref{lambertw:eqAllgLoes} trotzdem noch übersichtlich bleibt, wurden \(\eta\) und \(r_0\) wie folgt definiert:
+	\begin{equation}
+		\eta
+		=
+		\left(\frac{x}{x_0}\right)^2
+		\:\:\text{und}\:\:
+		r_0
+		=
+		\sqrt{x_0^2+y_0^2}.
+	\end{equation}
+\end{itemize}
+Diese neue allgemein Funktion \eqref{lambertw:eqAllgLoes} weist immer noch die selbe Struktur wie die vorherig hergeleitete Funktion \eqref{lambertw:funkLoes} auf, einerseits einen quadratischen Teil der in \(\eta\) enthalten ist, anderseits den \(\operatorname{ln}\)-Teil. Aus dieser Ähnlichkeit kann geschlossen werden, dass sich \eqref{lambertw:eqAllgLoes} auf eine ähnliche Art verhalten wird.
+
+Nun sind wir soweit, dass wir eine \(y(x)\)-Beziehung für beliebige Anfangswerte darstellen können, unser erstes Ziel wurde erreicht. Ist das alles? Nein, wir können einen Schritt weiter gehen und uns Fragen: Ist es analytisch möglich herauszufinden, wo sich Verfolger und Ziel zu jedem Zeitpunkt befinden? Dieser Frage werden wir im nächsten Abschnitt nachgehen.
+
+\subsection{Funktion nach der Zeit 
+	\label{lambertw:subsection:FunkNachT}}
+Lieber Leser sei mir nicht böse, aber in diesem Abschnitt werde ich ein wenig mehr bei den algebraischen Umformungen ins Detail gehen. Dies hat auch einen bestimmten Grund, ich möchte den Einsatz einer speziellen Funktion aufzeigen, sowie auch wann und wieso diese vorkommt. Welche spezielle Funktion? Fragst du dich wahrscheinlich in diesem Moment. Nun, um diese Frage zu kurz zu beantworten, es ist "YouTube's favorite special function" laut dem Mathematiker Michael Penn, die Lambert-W-Funktion \(W(x)\) welche übrigens im Kapitel \ref{buch:section:lambertw} bereits beschrieben wurde.
+
+Also fangen wir an. Der erste Schritt ist es herauszufinden, wie die Zeitabhängigkeit wieder hinein gebracht werden kann. Dafür greifen wir auf die letzte Gleichung zu, in welcher \(t\) noch enthalten war, und zwar DGL \eqref{lambertw:DGLmitT}, welche zur Übersichtlichkeit hier nochmals aufgeführt wird:
+\begin{equation}
+	x y^{\prime} + t - y
+	= 0.
+	\label{lambertw:eqDGLmitTnochmals}
+\end{equation}
+Wie in \eqref{lambertw:eqDGLmitTnochmals} zu sehen ist, werden \(y\) und deren Ableitung \(y^{\prime}\) benötigt, diese sind:
+\begin{subequations}
+	\begin{align}
+		y
+		&=
+		\frac{1}{4}\left(\left(y_0+r_0\right)\eta+\left(r_0-y_0\right)\operatorname{ln}\left(\eta\right)-r_0+3y_0\right), \\
+		\label{lambertw:eqFunkUndAbleit1}
+		y^\prime
+		&=
+		\frac{1}{2}\left(\left(y_0+r_0\right)\frac{x}{x_0^2}+\left(r_0-y_0\right)\frac{1}{x}\right).
+	\end{align}
+	\label{lambertw:eqFunkUndAbleit}
+\end{subequations}
+Wenn man diese Gleichungen \ref{lambertw:eqFunkUndAbleit} in die DGL \label{lambertw:eqDGLmitTnochmals} einfügt, vereinfacht und nach \(t\) auflöst, dann ergibt sich folgenden Ausdruck:
+\begin{equation}
+	-4t
+	=
+	\left(y_0+r_0\right)\left(\eta-1\right)+\left(r_0-y_0\right)\operatorname{ln}\left(\eta\right).
+	\label{lambertw:eqFunkUndAbleitEingefuegt}
+\end{equation}
+In einem nächsten Schritt wird alles mit \(x\) auf die eine Seite gebracht, der Rest auf die andere Seite und anschliessend beidseitig exponentiert, was wie folgt aussieht:
+\begin{align}
+	-4t+\left(y_0+r_0\right)
+	&=
+	\left(y_0+r_0\right)\eta+\left(r_0-y_0\right)\operatorname{ln}\left(\eta\right), \\
+	e^{\displaystyle -4t+\left(y_0+r_0\right)}
+	&=
+	e^{\displaystyle \left(y_0+r_0\right)\eta}\cdot\eta^{\displaystyle \left(r_0-y_0\right)}.
+	\label{lambertw:eqMitExp}
+\end{align}
+Auf dem rechten Term von \eqref{lambertw:eqMitExp} beginnen wir langsam eine ähnliche Struktur wie \(\eta e^\eta\) zu erkennen, dies schreit nach der Struktur die benötigt wird um \(\eta\) mittels der Lambert-W-Funktion \(W(x)\) zu erhalten. Dies macht durchaus Sinn, wenn wir die Funktion \(x(t)\) finden wollen und \(W(x)\) die Umkehrfunktion von \(x e^x\) ist. 
+
+Die erste Sache die uns in \eqref{lambertw:eqMitExp} stört ist, dass \(\eta\) als Potenz da steht. Dieses Problem können wir loswerden, indem wir beidseitig mit \(\:\displaystyle \frac{1}{r_0-y_0}\:\) potenzieren:
+\begin{equation}
+	e^{\displaystyle \frac{-4t}{r_0-y_0}+\frac{y_0+r_0}{r_0-y_0}}
+	=
+	\eta\cdot e^{\displaystyle \frac{y_0+r_0}{r_0-y_0}\eta} .
+	\label{lambertw:eqOhnePotenz}
+\end{equation}
+Das nächste Problem auf welches wir in \eqref{lambertw:eqOhnePotenz} treffen ist, dass \(\eta\) nicht alleine im Exponent steht. Dies kann elegant mit folgender Substitution gelöst werden:
+\begin{equation}
+	\chi
+	=
+	\frac{y_0+r_0}{r_0-y_0}.
+	\label{lambertw:eqChiSubst}
+\end{equation}
+Es gäbe natürlich andere Substitutionen wie z.B. 
+\[\displaystyle \chi=\frac{y_0+r_0}{r_0-y_0}\cdot\eta,\] 
+die auf das selbe Ergebnis führen würden, aber \eqref{lambertw:eqChiSubst} liefert in einem Schritt die kompakteste Lösung. Also fahren wir mit der  Substitution \eqref{lambertw:eqChiSubst} weiter, setzen diese in die Gleichung \eqref{lambertw:eqOhnePotenz} ein und multiplizieren beidseitig mit \(\chi\). Daraus erhalten wir folgende Gleichung:
+\begin{equation}
+	\chi\cdot e^{\displaystyle \chi-\frac{4t}{r_0-y_0}}
+	=
+	\chi\eta\cdot e^{\displaystyle \chi\eta}.
+	\label{lambertw:eqNachSubst}
+\end{equation}
+Schön oder? Nun sind wir endlich soweit, dass wir die angedeutete Lambert-W-Funktion \(W(x)\)einsetzen können. Wenn wir beidseitig \(W(x)\) anwenden, dann erhalten wir folgenden Ausdruck:
+\begin{equation}
+	W\left(\chi\cdot e^{\displaystyle \chi-\frac{4t}{r_0-y_0}}\right)
+	=
+	\chi\eta.
+\end{equation}
+Nach dem Auflösen nach \(x\) welches in \(\eta\) enthalten ist, erhalten wir die gesuchte \(x(t)\)-Funktion \eqref{lambertw:eqFunkXNachT}. Dieses \(x(t)\) in Kombination mit \eqref{lambertw:eqFunkUndAbleit1} liefert die Position des Verfolgers zu jedem Zeitpunkt. Das Gleichungspaar \eqref{lambertw:eqFunktionenNachT}, besteht aus folgenden Gleichungen:
+\begin{subequations}
+	\begin{align}
+		\label{lambertw:eqFunkXNachT}
+		x(t)
+		&=
+		x_0\cdot\sqrt{\frac{W\left(\chi\cdot e^{\displaystyle \chi-\frac{4t}{r_0-y_0}}\right)}{\chi}}, \\
+		\label{lambertw:eqFunkYNachT}
+		y(x(t))
+		=
+		y(t)
+		&=
+		\frac{1}{4}\left(\left(y_0+r_0\right)\left(\frac{x(t)}{x_0}\right)^2+\left(r_0-y_0\right)\operatorname{ln}\left(\left(\frac{x(t)}{x_0}\right)^2\right)-r_0+3y_0\right).
+	\end{align}
+	\label{lambertw:eqFunktionenNachT}
+\end{subequations}
+Nun haben wir unser letztes Ziel erreicht und sind in der Lage eine Verfolgung rechnerisch sowie graphisch zu repräsentieren.
+ 
+Wir sind aber noch nicht ganz fertig, ich muss gestehen, dass ich in diesem Abschnitt einen wichtigen Teil verschwiegen habe. Und zwar wieso, dass ich schon bei der Gleichung \eqref{lambertw:eqFunkUndAbleitEingefuegt} wusste, dass man nach einigen Umformungen die Lambert-W-Funktion eingesetzt werden kann.
+Der Grund dafür ist die Struktur
+\begin{equation}
+	y
+	=
+	p(x) +\operatorname{ln}(x),
+	\label{lambertw:eqEinsatzLambW}
+\end{equation}
+bei welcher \(p(x)\) eine beliebige Potenz von \(x\) darstellt. 
+
+Jedes mal wenn \(x\) gesucht ist und in einer Struktur der Art \eqref{lambertw:eqEinsatzLambW} vorkommt, dann kann mit ein paar Umformungen die Struktur \(f(x)e^{f(x)}\) erzielt werden. Wie bereits in diesem Abschnitt \ref{lambertw:subsection:FunkNachT} gezeigt wurde, kann \(x\) nun mittels der \(W(x)\)-Funktion aufgelöst werden. Erstaunlicherweise ist \eqref{lambertw:eqEinsatzLambW} eine Struktur die oftmals vorkommt, was die Lambert-W-Funktion so wichtig macht.
