Title: Introduction to Coxeter Groups

Abstract: Coxeter groups appear in many areas of mathematics and form the basis for the theory of buildings (which will be the focus of the topology seminar this term). Coxeter groups can be defined geometrically or algebraically. I will give both definitions and lots of examples, and I will discuss the connection between the algebra and the geometry. No prior knowledge of Coxeter groups will be assumed.
