SUMMARY:Commensurability of right-angled Artin groups - Ilya Kazachkov (Bi

DESCRIPTION:In this talk we address classification of right-angled Artin g
 roups (RAAGs) up to commensurability. We show that there are infinitely ma
 ny commensurability classes of quasi-isometric RAAGs and classify commensu
 rability for RAAGs defined by trees of diameter 4.
