| 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. | |||
