چکیده

A Coxeter system is called skew-angled if its Coxeter matrix contains no entry equal to 2. In this paper we prove rigidity results for skew-angled Coxeter groups. As a consequence of our results we obtain that skew-angled Coxeter groups are rigid up to diagram twisting.

Rigidity of Right-angled Coxeter Groups

In mathematics, a group is the set of symmetries of an object. Coxeter groups are a broad and natural class of groups that are related to reflectional symmetries. Each Coxeter group is determined by a diagram, called a labeled graph, that encodes algebraic information about the group. In general, two different labeled graphs can give rise to the same group. It is therefore natural to ask: are t...

A Letter to the Seminario Teoria de Grupos

My friend and collaborator Mauricio Gutierrez asked me to record the following thoughts to provide a discussion point for your seminar. Herein I sketch an argument which proves the rigidity of right-angled Coxeter groups. The rigidity of right-angled Coxeter groups is a special case of the Even Rigidity Theorem which appears in Michael Laurence’s Ph.D. thesis [5] and Patrick Bahls’ Ph.D. thesis...

AN ABSTRACT OF THE DISSERTATION OF Anton Kaul for the degree Doctor of Philosophy in Mathematics presented on May 3, 2000. Title: Rigidity for a Class of Coxeter Groups Abstract approved:

approved: William A. Bogley A Coxeter group W is said to be rigid if, given any two Coxeter systems (W,S) and (W,S ′), there is an automorphism ρ of W which carries S to S ′ In this dissertation we review rigidity results of D. Radcliffe [29] and of R. Charney and M. Davis [11], noting that certain restrictions must be placed on the Coxeter group in order to obtain rigidity. Radcliffe examined ...

Centralizers of Coxeter Elements and Inner Automorphisms of Right-Angled Coxeter Groups

Let W be a right-angled Coxeter group. We characterize the centralizer of the Coxeter element of a finite special subgroup of W. As an application, we give a solution to the generalized word problem for Inn(W ) in Aut(W ). Mathematics Subject Classification: 20F10, 20F28, 20F55
