Right-angled Artin groups (RAAGs) are an important class of objects of study in geometric group theory. It is interesting to know which groups are isomorphic to a RAAG. In this talk, we will explore how to recognize a Bestvina–Brady group as a RAAG. In particular, I will focus on Bestvina–Brady groups defined on 2-dimensional flag complexes. This is joint work with Lorenzo Ruffoni.
