-        \begin{itemize}
-            \item \alert{$\emptyset$} ist ein regulärer Ausdruck
-            \item \alert{$\epsilon$} ist ein regulärer Ausdruck
-            \item Für alle $a \in \Sigma$ ist \alert{$a$} ein regulärer Ausdruck
-            \item Sind $\alpha$ und $\beta$ reguläre Ausdrücke, dann auch

-                    \item[Konkatenation] \alert{$\alpha\beta$}
