Coxeter Groups and Geometric Manifolds

Sydney, Australia

8 October 2004

Geometric manifolds are spaces in which one can do geometry locally, where "geometry" is interpreted in a suitable way. Coxeter groups are an abstract generalisation of groups generated by reflections that arise classically. I will give a brief survey of some of the questions one might want to ask about geometric manifolds, and see how the theory of Coxeter groups can be used to provide some answers. The talk will be of a fairly elementary nature.
