Title:  Distinguishing residually finite groups by their finite quotients

Abstract:  By definition, a residually finite group has a large supply of finite quotient groups. A natural question is to what extent this collection of finite quotients "determines" the group. For example, an old, and basic question is, if G is a residually finite group with the same collection of finite quotient groups as a free group F of rank r, is G isomorphic to F? This talk will discuss this question for various classes of groups G as well as some other related questions.
