Title:
======
The vertices and sources of the natural simple module
for the alternating group in even characteristic

Abstract:
=========
For $n\geq 5$ the natural permutation module for the alternating
group $\mathfrak{A}_n$ has a unique non-trivial composition factor,
being called its natural simple module. We determine the vertices
and sources of the natural simple $\mathfrak{A}_n$-module
over fields of characteristic $2$.
