Finite groups of untwisted outer automorphisms of RAAGs
Corey Bregman, Ruth Charney, Karen Vogtmann
For any right-angled Artin group , Charney--Stambaugh--Vogtmann showed that the subgroup generated by Whitehead automorphisms and inversions act…
The Artin monoid Cayley graph
Rachael Boyd, Ruth Charney, Rose Morris-Wright +1
In this paper we investigate properties of the Artin monoid Cayley graph. This is the Cayley graph of an Artin group with respect to the (infinite) generating set given by th…
A Deligne complex for Artin Monoids
Rachael Boyd, Ruth Charney, Rose Morris-Wright
In this paper we introduce and study some geometric objects associated to Artin monoids. The Deligne complex for an Artin group is a cube complex that was introduced by the second…
Outer space for RAAGs
Corey Bregman, Ruth Charney, Karen Vogtmann
For any right-angled Artin group we construct a finite-dimensional space on which the group of outer automorphisms of acts with finite…
Artin groups of infinite type: trivial centers and acylindical hyperbolicity
Ruth Charney, Rose Morris-Wright
While finite type Artin groups and right-angled Artin groups are well-understood, little is known about more general Artin groups. In this paper we use the action of an infinite ty…
Searching for Hyperbolicity
Ruth Charney
This is an expository paper, based on by a talk given at the AWM Research Symposium 2017. It is intended as a gentle introduction to geometric group theory with a focus on the noti…
