Abstract
Finitely generated groups carry both an algebraic and a geometric structure, and to study such groups, one may study both algebraic and geometric classifications. More specifically, two fundamental problems in geometric group theory are to characterize the abstract commensurability and quasi-isometry classes among finitely generated groups. I will discuss these questions and present a solution within the setting of certain amalgamated free products of surface groups.
