Bi-exactness of relatively hyperbolic groups
Koichi Oyakawa; Vanderbilt University
Bi-exactness is an analytic property of groups defined by Ozawa and of fundamental importance to the study of operator algebras. In this talk, I will show that finitely generated relatively hyperbolic groups are bi-exact if and only if all peripheral subgroups are bi-exact. This is a generalization of Ozawa's result which claims that finitely generated relatively hyperbolic groups are bi-exact if all peripheral subgroups are amenable.
