Geoghegan stacks and finiteness properties of groups

Benno Kuckuck
(Oxford University)
Abstract

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.
