\begin{abstract}
This short article is a clean starting point for a paper: a title block, an
abstract, a couple of sections, some mathematics, and a bibliography wired up
through BibTeX. Replace the text with your own.
\end{abstract}

\section{Introduction}
Open with the problem and why it matters. Citations such as
Knuth~\cite{knuth1984} and cross-references all work out of the box.

\section{A Result}
For a right triangle with legs $a$ and $b$ and hypotenuse $c$,
\begin{equation}
  a^2 + b^2 = c^2 .
\end{equation}

\section{Conclusion}
Summarise the contribution and point to what comes next.
