Coxeter Groups

open access: yes, 2017
This chapter considers Coxeter groups and how to find a space on which a group acts by building a space using combinatorics from the group. It first describes groups generated by reflections, focusing on Euclidean spaces and showing that some natural, beautiful, and important subsets of Euclidean spaces have symmetric groups that are discrete and are ...

On the Efficiency of Coxeter Groups

Bulletin of the London Mathematical Society, 1997
If \(G\) is a finitely presented group and \(K\) is any \((G,2)\)-complex (that is, a finite 2-complex with fundamental group \(G\)), then it is well known that \(\chi(K)\geq 1-rk(H_1(G))+d(H_2(G))\). If equality holds for some \((G,2)\)-complex \(K\) then \(G\) is called efficient.
