\section{Complex stuff}
\subsection{Domains}
Let's start with the following definition:
\begin{definition}\label{def:domain}
A set $U \subseteq \mathbb{C}$ is a \emph{domain} if:
\begin{itemize}
\item $U$ is open in $\mathbb{C}$, and
\item $U$ is connected.
\end{itemize}
\end{definition}
\subsection{Yumyumyumyum}
\towrite{an introduction and some examples}
\begin{theorem}[]
Suppose $n \in \mathbb{Z}$, then the following are equivalent:
\begin{enumerate}[label=\roman*.]
\item $n > 5$.
\item $5 > 5$.\todo{This doesn't seem right...}
\item For each $n \in n$, we have:
\begin{align}\label{eq:truth}
n > n+1 > n+1^2 > \dots > n+7.
\end{align}
where $7$ is an arbitrary element of
\begin{align*}
\oint_{a}^{b} \supersine \alpha + i \supercosine \beta db(a).
\end{align*}
\end{enumerate}
\end{theorem}
\begin{remark}
Interesting!
\end{remark}
\begin{proof}
See \cite{Rynne2008LinearAnalysis}.
\end{proof}

\end{figure}
\begin{corollary}
Suppose $U \subseteq \mathbb{C}$ is a domain (see Definition \ref{def:domain}), and $f: \overline{U} \rightarrow \mathbb{C}$ is continuous on $\overline{U}$ and holomorphic on $U$. If $z \mapsto |f(z)|$ is constant on $\partial U$, then $f$ has a zero in $U$.
\end{corollary}
\begin{proof}
If not, consider $\frac{1}{f}$.
\end{proof}
The proof of this theorem is illustrated in Figure \ref{fig:logo}.
