Last week, Katie introduced us to Coxeter groups as given by generators and relations, with an emphasis on permutations and words. In this talk, I'll approach Coxeter groups from a geometric perspective. I'll go into detail on how Coxeter groups abstract the idea of reflection symmetry. I'll also discuss the classification of finite Coxeter groups, and how it relates to other classifications of nicely symmetric objects, like regular polytopes and tilings. And something from another previous student combinatorics talk will make a surprise reappearance.

Although I'll reference last week's talk, you don't need to have attended that one to understand this one. Speaker(s): Will Dana (University of Michigan)
