\section{Mathematics}
\subsection{Theorem}
\begin{frame}{Mathematics}
\begin{theorem}[Fermat's little theorem]
For a prime~\(p\) and \(a \in \mathbb{Z}\) it holds that \(a^p \equiv a \pmod{p}\).
\end{theorem}
\begin{proof}
The invertible elements in a field form a group under multiplication.
In particular, the elements
\begin{equation*}
1, 2, \ldots, p - 1 \in \mathbb{Z}_p
\end{equation*}
form a group under multiplication modulo~\(p\).
This is a group of order \(p - 1\).
For \(a \in \mathbb{Z}_p\) and \(a \neq 0\) we thus get \(a^{p-1} = 1 \in \mathbb{Z}_p\).
The claim follows.
\end{proof}
\end{frame}
\subsection{Example}
\begin{frame}{Mathematics}
\begin{example}
The function \(\phi \colon \mathbb{R} \to \mathbb{R}\) given by \(\phi(x) = 2x\) is continuous at the point \(x = \alpha\),
because if \(\epsilon > 0\) and \(x \in \mathbb{R}\) is such that \(\lvert x - \alpha \rvert < \delta = \frac{\epsilon}{2}\),
then
\begin{equation*}
\lvert \phi(x) - \phi(\alpha)\rvert = 2\lvert x - \alpha \rvert < 2\delta = \epsilon.
\end{equation*}
\end{example}
\end{frame}
\section{Highlighting}
\SectionPage
\begin{frame}{Highlighting}
Some times it is useful to \alert{highlight} certain words in the text.
\begin{alertblock}{Important message}
If a lot of text should be \alert{highlighted}, it is a good idea to put it in a box.
\end{alertblock}
It is easy to match the \structure{colour theme}.
\end{frame}
\section{Lists}
\begin{frame}{Lists}
\begin{itemize}
\item
Bullet lists are marked with a grey box.
\end{itemize}
\begin{enumerate}
\item
\label{enum:item}
Numbered lists are marked with a white number inside a grey box.
\end{enumerate}
\begin{description}
\item[Description]
highlights important words with grey text.
\end{description}
Items in numbered lists like \enumref{enum:item} can be referenced with a grey box.
\begin{example}
\begin{itemize}
\item
Lists change colour after the environment.
\end{itemize}
\end{example}
\end{frame}
\section{Effects}
\begin{frame}{Effects}
\begin{columns}[onlytextwidth]
\begin{column}{0.49\textwidth}
\begin{enumerate}[<+-|alert@+>]
\item
Effects that control

are specified with <> and a list of slides.
\end{enumerate}
\begin{theorem}<2>
This theorem is only visible on slide number 2.
\end{theorem}
\end{column}
\begin{column}{0.49\textwidth}
Use \textbf<2->{textblock} for arbitrary placement of objects.

It creates a box
with the specified width (here in a percentage of the slide's width)
and upper left corner at the specified coordinate (x, y)
(here x is a percentage of width and y a percentage of height).
\end{column}
