Geoghegan's stack construction is a tool for analysing groups
that act on simply connected CW complexes, by providing a topological
description in terms of cell stabilisers and the quotient complex,
similar to what Bass-Serre theory does for group actions on trees. We
will introduce this construction and see how it can be used to give
results on finiteness properties of groups.
