Homology of some Artin and twisted Artin Groups

Journal of K-Theory, 2009
AbstractWe begin the paper with a simple formula for the second integral homology of a range of Artin groups. The formula is derived from a polytopal classifying space. We then introduce the notion of atwisted Artin groupand obtain polytopal classifying spaces for a range of such groups.

On Generalized Homology of Artin Groups

Journal of Mathematical Sciences, 2003
Generalized braid groups \(\text{Br}({\mathcal D}_\infty)\), \(\text{Br}({\mathcal C}_m)\) and \(\text{Br}^g_\infty\) (braids of an infinite number of strings in a genus \(g\) handlebody) are considered and the Morava \(K\)-theory \(K(n)_*(\text{Br}({\mathcal D}_\infty))\), \(K(n)_*(\text{Br}^g_\infty)\), the Brown-Peterson homology \(\text{BP}_*(\text{

Rigidity of Coxeter Groups and Artin Groups

Geometriae Dedicata, 2002
A Coxeter group is called rigid if it cannot be defined by two nonisomorphic diagrams. The authors show that an example of a nonrigid Coxeter group belongs to a ``diagram twisting operation'' and that Coxeter groups, belonging to twisted diagrams, are isomorphic. A Coxeter system \((W,S)\) is called reflection rigid, if every Coxeter generating set \(S'

Geometric Invariants for Artin Groups

Proceedings of the London Mathematical Society, 1997
The Bieri-Neumann-Strebel invariant of a finitely generated group \(G\) determines, among other things, whether or not a given normal subgroup \(N\), with \(G/N\) abelian, is finitely generated. We examine the BNS-invariants of ``Pride groups'', a large class of groups containing the Artin groups; in particular we establish a criterion which implies ...

Artin braid groups and homotopy groups

Proceedings of the London Mathematical Society, 2009
We study the Brunnian subgroups and the boundary Brunnian subgroups of the Artin braid groups. The general higher homotopy groups of the sphere are given by mirror symmetric elements in the quotient groups of the Artin braid groups modulo the boundary Brunnian braids, as well as given as a summand of the center of the quotient groups of Artin pure ...
