\section{The main conjecture}

\begin{conj}
  This template will prove useful. Here is a custom command: $\la$.
\end{conj}

\begin{axio}
  Here is a custom theorem style.
\end{axio}

Some references I would like to cite are~\cite{Macdonald, AHK, Propp, Williams, Postnikov}.

% A longer acknowledgment at the end looks like this:

\longthanks{We thank B.~Pascal for some interesting comments on an earlier version of this manuscript.}
