This template does not comply with the design manual at the University of Oslo from 2022.
Beamer theme for the Department of Mathematics at the University of Oslo.
This theme uses the aspect ratio 16:9, which fills out more of the computer screen than the standard 4:3 ratio. It is intended for digital lectures, rather than canvas presentations.

\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}
You can also highlight with the \structure{structure} colour.
\end{frame}
\section{Lists}
\begin{frame}{Lists}
\begin{itemize}
\item
Bullet lists are marked with a red dot.
\end{itemize}
\begin{enumerate}
\item
\label{enum:item}
Numbered lists are marked with a white number inside a red disc.
\end{enumerate}
\begin{description}
\item[Description]
highlights important words with red text.
\end{description}
Items in numbered lists like \enumref{enum:item} can be referenced with a red disc.
\end{frame}

It creates a box

and upper left corner at the specified coordinate (x, y)
(here x is a percentage of width and y a percentage of height).
