Title
The RAAG Recognition Problem for Bestvina--Brady Groups
Abstract
When a group is finitely presented by commutators, is it isomorphic to a right-angled Artin group (RAAG)?
Bridson recently showed that there is no algorithm to determine whether such a group is a
RAAG. However, this recognition problem remains interesting for certain classes of groups.
In this talk, I will discuss the RAAG recognition problem for Bestvina–Brady groups from a graph theory point of view.
This is joint work with Lorenzo Ruffoni.
