		<summary type="html">&lt;p&gt;Die Seite wurde neu angelegt: „{{Scripthinweis|Quantenmechanik|6|3}}  &amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Grundpostulat &amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt; der speziellen Relativitätstheorie:  kein Inertialsystem ist gegenüber einem anderen ausgezei…“&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Neue Seite&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{Scripthinweis|Quantenmechanik|6|3}}&lt;br /&gt;
&lt;br /&gt;
&amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Grundpostulat &amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt; der speziellen Relativitätstheorie:&lt;br /&gt;
&lt;br /&gt;
kein Inertialsystem ist gegenüber einem anderen ausgezeichnet ( es existiert kein Ruhezustand)&lt;br /&gt;
&lt;br /&gt;
Einstein, 1904&lt;br /&gt;
&lt;br /&gt;
Eine Bewegung ist vom Ruhezustand nicht zu unterscheiden, so lange sie nicht zu einer anderen Bewegung in Relation gesetzt wird !&lt;br /&gt;
&lt;br /&gt;
Die Lichtgeschwindigkeit c ist in jedem Inertialsystem gleich !!&lt;br /&gt;
&lt;br /&gt;
Also: &amp;lt;math&amp;gt;{{\bar{r}}^{2}}-{{c}^{2}}{{t}^{2}}=\bar{r}{{\acute{\ }}^{2}}-{{c}^{2}}t{{\acute{\ }}^{2}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Kugelwellen mit der Ausbreitungsgeschwindigkeit c sind Lorentz- invariant !&lt;br /&gt;
&lt;br /&gt;
&amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Formalisierung&amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Der raumzeitliche Abstand&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left( ds \right)}^{2}}:={{\left( cdt \right)}^{2}}-{{\left( d\bar{r} \right)}^{2}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
ist in jedem Bezugssystem gleich, bleibt also invariant bei Transformationen zwischen Inertialsystemen ( Lorentz- Transformationen !)&lt;br /&gt;
&lt;br /&gt;
Man kann &amp;lt;math&amp;gt;{{\left( ds \right)}^{2}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
als Skalarprodukt von Vierervektoren mit 3 Orts- und einer Zeitkomponente schreiben.&lt;br /&gt;
&lt;br /&gt;
Diese Vektoren leben im Minkowski- Raum V (Spannen diesen auf).&lt;br /&gt;
&lt;br /&gt;
V ist natürlich nicht euklidisch. Sonst würde Pythagoras gelten!&lt;br /&gt;
&lt;br /&gt;
Dann benutze man den Formalismus der LINEAREN ORTHOGONALEN Transformationen, unter denen das Skalarprodukt invariant ist:&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Def.:  &amp;#039;&amp;#039;&amp;#039;Als kontravariante Komponenten des 4-Zeit-Orts-Vektors ( Vierervektors) bezeichnet man:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{x}^{0}}:=ct \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{x}^{\alpha }},\alpha =1,2,3 \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Zeitkomponente und kartesische Komponenten des Ortsvektors &amp;lt;math&amp;gt;\bar{r}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
es schreibt sich&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left( ds \right)}^{2}}={{\left( d{{x}^{0}} \right)}^{2}}-{{\left( d{{x}^{1}} \right)}^{2}}-{{\left( d{{x}^{2}} \right)}^{2}}-{{\left( d{{x}^{3}} \right)}^{2}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Def.: &amp;#039;&amp;#039;&amp;#039;als kovariante Komponenten des 4-Zeit-Orts-Vektors ( Vierervektors) bezeichnet man:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{x}_{0}}:={{x}^{0}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{x}_{\alpha }}:=-{{x}^{\alpha }}\alpha =1,2,3 \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Der kovariante Vektor ist Element des dualen Vektorraums &amp;lt;math&amp;gt;\tilde{V}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\tilde{V}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
ist der Raum der linearen Funktionale l, die V auf R abbilden:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\tilde{V}=\left\{ lineareFunktionale\quad l:V-&amp;gt;R \right\}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
es schreibt sich&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{\left( ds \right)}^{2}}=d{{x}^{0}}d{{x}_{0}}+d{{x}^{1}}d{{x}_{1}}+d{{x}^{2}}d{{x}_{2}}+d{{x}^{3}}d{{x}_{3}}=d{{x}^{i}}d{{x}_{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Natürlich mit Summenkonvention über i=0,1,2,3,...&lt;br /&gt;
&lt;br /&gt;
Wenn ein Index oben ( kontravariant) und ein Index unten ( kovariant) steht.&lt;br /&gt;
&lt;br /&gt;
====Verallgemeinerung====&lt;br /&gt;
Für beliebige 4- Vektoren &amp;lt;math&amp;gt;{{a}^{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
gilt:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{a}_{0}}={{a}^{0}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{a}_{\alpha }}=-{{a}^{\alpha }}\quad \alpha =1,2,3 \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Lorentz- Invariante lassen sich als Skalarprodukt &amp;lt;math&amp;gt;{{a}_{i}}{{a}^{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
schreiben:&lt;br /&gt;
&lt;br /&gt;
=====Der d´Alemebert-Operator=====&lt;br /&gt;
&amp;lt;math&amp;gt;\#:=\Delta -\frac{1}{{{c}^{2}}}\frac{{{\partial }^{2}}}{\partial {{t}^{2}}}=-\frac{\partial }{\partial {{x}^{i}}}\frac{\partial }{\partial {{x}_{i}}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Mit&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{\partial }{\partial {{x}^{i}}}=\left( \frac{1}{c}\frac{\partial }{\partial t},\frac{\partial }{\partial {{x}^{\alpha }}} \right)=:{{\partial }_{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
kovariant&lt;br /&gt;
&lt;br /&gt;
Die Eigenschaft der Kovarianz wird später aus dem Transformationsverhalten begründet !&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\frac{\partial }{\partial {{x}_{i}}}=\left( \frac{1}{c}\frac{\partial }{\partial t},-\frac{\partial }{\partial {{x}^{\alpha }}} \right)=:{{\partial }^{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
kontravariant&lt;br /&gt;
&lt;br /&gt;
-&amp;gt; Die Eigenschaft der Kontravarianz wird später aus dem Transformationsverhalten begründet !&lt;br /&gt;
&lt;br /&gt;
&amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Also:&amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\Rightarrow \ \#=-{{\partial }_{i}}{{\partial }^{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Vierergeschwindigkeit&amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{u}^{i}}:=\frac{d{{x}^{i}}}{ds} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; ds={{\left( d{{x}^{i}}d{{x}_{i}} \right)}^{\frac{1}{2}}}={{\left( {{c}^{2}}d{{t}^{2}}-{{\left( d\bar{r} \right)}^{2}} \right)}^{\frac{1}{2}}}=c{{\left[ 1-{{\left( \frac{1}{c}\frac{d\bar{r}}{dt} \right)}^{2}} \right]}^{\frac{1}{2}}}dt \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; ds:={{\left( 1-{{\beta }^{2}} \right)}^{\frac{1}{2}}}dt=\frac{c}{\gamma }dt \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dabei gilt:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; \beta :=\frac{v}{c}=\frac{1}{c}\left| \frac{d\bar{r}}{dt} \right| \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; \gamma :=\frac{1}{\sqrt{1-{{\beta }^{2}}}} \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Also:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{u}^{0}}=\gamma  \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{u}^{\alpha }}=\frac{\gamma }{c}{{v}^{\alpha }}=\frac{1}{c}\frac{d{{x}^{\alpha }}}{d\tau } \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Mit der Eigenzeit&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;d\tau =\frac{dt}{\gamma }&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Die Eigenzeit ist als die Zeit im momentanen Ruhesystem zu verstehen !&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{u}^{i}}{{u}_{i}}=\frac{d{{x}^{i}}d{{x}_{i}}}{d{{s}^{2}}}=1&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
ist nicht vom Bezugssystem abhängig, also invariant !&lt;br /&gt;
&lt;br /&gt;
=====Viererimpuls=====&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{p}^{i}}:={{m}_{0}}c{{u}^{i}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; \Rightarrow {{p}^{i}}{{p}_{i}}={{m}_{0}}^{2}{{c}^{2}}{{u}^{i}}{{u}_{i}}={{m}_{0}}^{2}{{c}^{2}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{p}^{0}}=\frac{{{m}_{0}}c}{\sqrt{1-{{\left( \frac{v}{c} \right)}^{2}}}}=m(v)c={{p}_{0}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{p}^{\alpha }}=\frac{{{m}_{0}}{{v}^{\alpha }}}{\sqrt{1-{{\left( \frac{v}{c} \right)}^{2}}}}=m(v){{v}^{\alpha }}=-{{p}_{\alpha }} \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Physikalische Bedeutung von &amp;lt;math&amp;gt;{{p}^{0}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&lt;br /&gt;
&lt;br /&gt;
Mit der 4-er Kraft: &amp;lt;math&amp;gt;{{k}^{i}}:=\frac{d}{d\tau }{{p}^{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
folgt die Leistungsbilanz:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{k}^{i}}{{u}_{i}}=\left[ \frac{d}{d\tau }\left( {{m}_{0}}c{{u}^{i}} \right) \right]{{u}_{i}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Mit Hilfe des Energiesatz kann dies umgewandelt werden zu&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{k}^{i}}{{u}_{i}}=\frac{{{m}_{0}}c}{2}\frac{d}{d\tau }\left( {{u}^{i}}{{u}_{i}} \right)=0 \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{u}^{i}}{{u}_{i}}=1 \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
also lorentzinvariant !&lt;br /&gt;
&lt;br /&gt;
&amp;lt;u&amp;gt;&amp;#039;&amp;#039;&amp;#039;Außerdem gilt:&amp;#039;&amp;#039;&amp;#039;&amp;lt;/u&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{k}^{i}}{{u}_{i}}=\frac{d}{d\tau }\left( {{p}^{0}} \right){{u}_{0}}+{{k}^{\alpha }}{{u}_{\alpha }}=\gamma \frac{d}{d\tau }\left( {{p}^{0}} \right)+\frac{\gamma }{c}{{k}^{\alpha }}{{v}_{\alpha }}=\frac{\gamma }{c}\left[ \frac{d}{d\tau }\left( c{{p}^{0}} \right)-\bar{k}\bar{v} \right]=0 \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; \left( c{{p}^{0}} \right)=Energie \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; \bar{k}\bar{v}=Leistung \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Somit jedoch folgt eine Bestimmungsgleichung an &amp;lt;math&amp;gt;\left( {{p}^{0}} \right)=\frac{E}{c}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
, also &amp;lt;math&amp;gt;E=\frac{{{m}_{0}}{{c}^{2}}}{\sqrt{\left( 1-{{\beta }^{2}} \right)}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
als Energie eines relativistischen Teilchens.&lt;br /&gt;
&lt;br /&gt;
Das Skalarprodukt des Viererimpulses liefert lorentzinvariant &amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{p}^{i}}{{p}_{i}}=\frac{{{E}^{2}}}{{{c}^{2}}}-{{{\bar{p}}}^{2}}={{m}_{0}}^{2}{{c}^{2}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; \bar{p}=\frac{{{m}_{0}}\bar{v}}{\sqrt{1-{{\beta }^{2}}}} \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Also folgt an die Energie:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{E}^{2}}={{m}_{0}}^{2}{{c}^{4}}+{{c}^{2}}{{\bar{p}}^{2}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Dies ist die relativistsiche Energie- Impuls- Beziehung&lt;br /&gt;
&lt;br /&gt;
====Mathematischer Formalismus zur Tensorrechnung:====&lt;br /&gt;
Für Tensoren zweiter Stufe gilt:&lt;br /&gt;
&lt;br /&gt;
Möglich ist: &amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{A}^{ik}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{A}^{i}}_{k} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{A}_{i}}^{k} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{A}_{ik}} \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Es gilt:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{A}^{00}}={{A}^{0}}_{0}={{A}_{0}}^{0}={{A}_{00}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{A}^{10}}={{A}^{1}}_{0}=-{{A}_{1}}^{0}=-{{A}_{10}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{A}^{11}}=-{{A}^{1}}_{1}=-{{A}_{1}}^{1}={{A}_{11}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; usw... \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Die Spur eines Tensors ist dagegen wieder allgemein:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;spA={{A}^{i}}_{i}={{A}_{i}}^{i}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=====- er Einheitstensor=====&lt;br /&gt;
&amp;lt;math&amp;gt;{{\delta }^{k}}_{i}={{\delta }_{i}}^{k}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
wie beim Kronecker- Symbol 1 für i=k und sonst Null, also symmetrisch&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&amp;amp; {{\delta }_{i}}^{k}{{a}^{kl}}={{a}^{il}} \\&lt;br /&gt;

\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{g}^{ik}}:={{\delta }^{ik}}={{\delta }^{i}}_{k}\quad f\ddot{u}r\ k=0 \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{g}^{ik}}:={{\delta }^{ik}}=-{{\delta }^{i}}_{k}\quad f\ddot{u}r\ k=1,2,3 \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{g}^{ik}}:={{\delta }^{ik}}=\left( \begin{matrix}&lt;br /&gt;
&lt;br /&gt;
1 &amp;amp; {} &amp;amp; {} &amp;amp; {}  \\&lt;br /&gt;
&lt;br /&gt;
{} &amp;amp; -1 &amp;amp; {} &amp;amp; {}  \\&lt;br /&gt;
&lt;br /&gt;
{} &amp;amp; {} &amp;amp; -1 &amp;amp; {}  \\&lt;br /&gt;
&lt;br /&gt;
{} &amp;amp; {} &amp;amp; {} &amp;amp; -1  \\&lt;br /&gt;
&lt;br /&gt;
\end{matrix} \right)={{g}_{ik}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{g}^{ik}}{{a}_{k}}={{\delta }^{ik}}{{a}_{k}}={{a}_{i}}\quad f\ddot{u}r\ i=0\Rightarrow {{a}_{i}}={{a}^{i}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{g}^{ik}}{{a}_{k}}={{\delta }^{ik}}{{a}_{k}}=-{{a}_{i}}\quad f\ddot{u}r\ i=1,2,3\Rightarrow -{{a}_{i}}={{a}^{i}} \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Also:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{g}^{ik}}{{a}_{k}}={{\delta }^{ik}}{{a}_{k}}={{a}^{i}}\quad f\ddot{u}r\ i=0,1,2,3&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Man spricht auch vom heben und Senken der Indices durch die Metrik !&lt;br /&gt;
&lt;br /&gt;
=====Lorentz- Trnsformationen ( linear, homogen) &amp;lt;math&amp;gt;\Sigma \to \Sigma \acute{\ }&amp;lt;/math&amp;gt;=====&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; x{{\acute{\ }}^{i}}={{U}^{i}}_{k}{{x}^{k}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{U}^{i}}_{k}=\left( \begin{matrix}&lt;br /&gt;
&lt;br /&gt;
\gamma  &amp;amp; -\beta \gamma  &amp;amp; 0 &amp;amp; 0  \\&lt;br /&gt;
&lt;br /&gt;
-\beta \gamma  &amp;amp; \gamma  &amp;amp; 0 &amp;amp; 0  \\&lt;br /&gt;

\end{matrix} \right) \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
für &amp;lt;math&amp;gt;v||{{x}^{1}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Somit:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;{{U}^{k}}_{i}=\left( \begin{matrix}&lt;br /&gt;
&lt;br /&gt;
\gamma  &amp;amp; \beta \gamma  &amp;amp; 0 &amp;amp; 0  \\&lt;br /&gt;
&lt;br /&gt;
\beta \gamma  &amp;amp; \gamma  &amp;amp; 0 &amp;amp; 0  \\&lt;br /&gt;

0 &amp;amp; 0 &amp;amp; 1 &amp;amp; 0  \\&lt;br /&gt;
&lt;br /&gt;
0 &amp;amp; 0 &amp;amp; 0 &amp;amp; 1  \\&lt;br /&gt;
&lt;br /&gt;
\end{matrix} \right)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Wobei &amp;lt;math&amp;gt;{{\gamma }^{2}}=\frac{1}{1-{{\beta }^{2}}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Damit läßt sich die Invarianz des Skalaprodukts leicht zeigen:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\begin{align}&lt;br /&gt;
&lt;br /&gt;
&amp;amp; a{{\acute{\ }}^{i}}={{U}^{i}}_{k}{{a}^{k}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; b{{\acute{\ }}^{i}}={{U}^{i}}_{k}{{b}^{k}}\Rightarrow b{{\acute{\ }}_{i}}={{U}_{ik}}{{b}^{k}}={{U}_{i}}^{k}{{b}_{k}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; a{{\acute{\ }}^{i}}b{{\acute{\ }}_{i}}={{U}^{i}}_{k}{{U}_{i}}^{l}{{a}^{k}}{{b}_{l}}=!={{a}^{k}}{{b}_{k}} \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; also\Rightarrow : \\&lt;br /&gt;
&lt;br /&gt;
&amp;amp; {{U}^{i}}_{k}{{U}_{i}}^{l}={{\delta }_{k}}^{l} \\&lt;br /&gt;
&lt;br /&gt;
\end{align}&amp;lt;/math&amp;gt;&lt;br /&gt;
