This chapter develops a theory of descent for buildings by assembling various results about Coxeter groups. It begins with the notation stating that W is an arbitrary group with a distinguished set of generators S containing only elements of order 2, with MS denoting the free monoid on the set S and l: MS → ℕ denoting the length function.

Abstract We describe the construction of a class of mappings in projective space C PN for any N. These mappings are non-linear representations of Coxeter groups by birational and therefore almost everywhere defined and invertible transformations. We give specific examples of the construction and exhibit algebraic invariants.

On Isomorphisms between Coxeter Groups
Designs, Codes and Cryptography, 2000The 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.

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 ...
