Isomorphisms Between Bestsvina--Brady Groups and Right-angled Artin Groups

Abstract

We give a combinatorial criterion for determining which Bestvina--Brady group is isomorphic to a right-angled Artin group.

There are errors in the proof of Theorem 3.1. The "finite simplicial graph" in the statement of Theorem 3.1 should be replaced with 2-trees. Results of this preprint have been revised in upcoming joint work
