On Isomorphisms between Coxeter Groups

Designs, Codes and Cryptography, 2000
The author exhibits two non-isomorphic connected Coxeter diagrams of rank 4 (with labels 3 and \(\infty\)) such that the corresponding Coxeter groups are isomorphic. For related results compare \textit{T. Brady, J. P. McCammond, B. Mühlherr} and \textit{W. D. Neumann} [Geom. Dedicata 94, No. 1, 91-109 (2002)] and \textit{B.

Linear Coxeter Groups

1995
Any discrete group W generated by reflections in a space of constant curvature X (discrete reflection group) can be described in terms of its fundamental region P,which is a convex polyhedron whose dihedral angles are proper submultiples of π. By immersing the space X in a linear space E (the ambient space), P extends to a convex polyhedral cone C p ...

Free Coxeter Groups

2017
This chapter, mostly taken from an article of Shi and Yang, contains the full description of cells and the proof of Lusztig’s Conjectures for free Coxeter groups (often called universal Coxeter groups).
