On the classification of generalized Baumslag-Solitar groups

Time: 9/23 Fri. 3:00-4:00P
Location: On zoom or at DH 249.
Speaker: Daxun Wang from SUNY Buffalo

Abstract: A generalized Baumslag-Solitar group (GBS group) is a group that acts on a tree with infinite cyclic edge and vertex stabilizers. Equivalently, it is the fundamental group of a graph of infinite cyclic groups. These groups have arisen in the study of splitting of groups. In this talk, we will discuss how to approach the group-theoretic classification of GBS groups and the current results of this problem.
