Coxeter groups, arithmetic reflection groups, and Vinberg’s algorithm
Michelle Chu, UCSB
Host: Neil Hoffman
[Abstract] [PDF]
Abstract: Coxeter groups and arithmetic reflection groups are broad classes of groups relevant to the study of hyperbolic manifolds. To make this connection more concrete we can build a fundamental domain for a hyperbolic reflection group using Vinberg's algorithm. In this expository talk I will introduce and discuss these ideas, which will serve to give some of the important background for my talk at Redbud later in the week.
