Geometric Realization of Coxeter Groups
Student-Run Geometry/Topology Seminar| Speaker: | Yvonne Lai, UC Davis |
| Location: | 2112 MSB |

We understand geometric reflection groups through their actions on constant curvature spaces. But given any Coxeter group W, is there a space on which W acts nicely? Yes: the Davis-Moussong complex. We will construct the complex in this talk and sketch why it is CAT(0).
