Right-angled Coxeter groups as a source of examples Seminar

Coxeter groups are groups generated by reflections; right-angled Coxeter groups are the simplest ones in which any two reflection planes are either parallel or perpendicular. I shall explain some of the ways in which these groups give rise to interesting examples in a range of areas, following the seminal work of Mike Davis. If I say anything original it will be joint work with Nansen Petrosyan.
