\framesubtitle{A short introduction to the HRIA theme}

The \textbf{HRIA Theme} (used as \texttt{\textbackslash usetheme\{hria\}}) is a
modern theme for Beamer based on some exiting HRIA documents\footnotemark[1].

\bigskip
It comes with a few nifty features:
\begin{itemize}
    \item Use of the HRIA colors consistent with other documents.
    \item Clean typography and spacing.
    \item Customized environments.
\end{itemize}

\bigskip
Separate parts are available as e.g. \texttt{\textbackslash usecolortheme\{hria\}}!

\begin{frame}{HRIA Theme: Colors and Fonts}

This theme uses the \emph{Adobe Source Sans Pro} font. This is a clean \emph{sans serif}
font from Adobe that is freely available.

\bigskip
The theme has three standard colors:
\begin{itemize}
    \item A nice \textcolor{HRIALightBlue}{\textbf{light blue}} (\texttt{HRIALightBlue}).
    \item A bolder \textcolor{HRIADarkBlue}{\textbf{dark blue}} (\texttt{HRIADarkBlue}).
    \item An attention grabbing \textcolor{HRIAGreen}{\textbf{green}}
    (\texttt{HRIAGreen})!
    \item Variants \texttt{color!x} can also be used to darken or lighten them
\end{itemize}

\bigskip
These can be used for emphasizing \textcolor{HRIALightBlue}{text} or for
more obvious \alert{alerts}. Standard \textbf{bold} and \textit{italic} emphasis
can of course also be used!
\end{frame}

\begin{frame}{HRIA Theme: Blocks}
We have various standard Beamer blocks styled in a pleasing fashion.

\begin{block}{Block 1}
Some block block.
\end{block}

\begin{alertblock}{Alert 1}
Some alert block.
\end{alertblock}

\begin{exampleblock}{Example 1}
Some example block.
\end{exampleblock}
\end{frame}

\begin{frame}{HRIA Theme: Lists}
\textbf{Itemize}

\begin{itemize}
    \item Itemize lists are nicely customized ...
    \begin{itemize}
        \item All the way down ...
        \begin{itemize}
            \item To the third level!
        \end{itemize}
    \end{itemize}
\end{itemize}

\textbf{Enumerate}

\begin{enumerate}
    \item We can also enumerate!
    \item Many things!
    \item It's great!
\end{enumerate}

\textbf{Description}

\begin{description}
    \item[HRIA] And describe the project in exquisite detail, so that we
        can capture all its multiline greatness!
\end{description}

\begin{frame}{HRIA Theme: Animations}

You can do a standard reveal with \texttt{[<+->]}.
\bigskip

\begin{itemize}[<+->]
    \item This is\alert<4>{ really} important.
    \item Now this.
    \item And now this.
\end{itemize}

\visible<4->{
\pause
\bigskip
You can also do an alerted reveal with \texttt{[<+- | alert@+>]}.
\bigskip

\begin{itemize}[<+- | alert@+>]
    \item This is important.
    \item Now this.
    \item And now this.

\framesubtitle{Gamma function definitions}

\begin{itemize}
    \item Euler's integral definition:
    \[
    \Gamma(z) = \int_0^{\infty} t^{z-1} e^{-t} \, \mathrm{d}t, \qquad \operatorname{Re}(z) > 0.
    \]
    \item Euler's product definition:
    \[
    \Gamma(z) = \frac{1}{z} \prod_{n=1}^{\infty} \frac{\left(1 + \tfrac{1}{n}\right)^z}{1 + \tfrac{z}{n}}.
    \]
    \item Weierstrass' product definition (use the Euler--Mascheroni constant $\gamma$):
    \[
    \frac{1}{\Gamma(z)} = z e^{\gamma z} \prod_{n=1}^{\infty} \left(1 + \frac{z}{n}\right) e^{-z/n}.
    \]
