distinguishing residually finite groups by their finite quotients
abstract:
in broad terms this talk will discuss how much information about a f.g. residually finite group is carried by the collection of its finite quotients. for example a precise question in this direction (and which has been open for many years) is: given a f.g. residually finite group g with the same collection of finite quotients as a free group of rank n, is g isomorphic to a free group of rank n?
