Title: “*Reflections
on the subject of algebraic extensions of finitely *

*generated fully
residually free groups.*”

Date: 3:30pm

Room: 920 Burnside

Abstract:

A group *G *is
fully residually free if for any finite number of

non-trivial elements
there exists a homomorphism from *G* to a free group *F* such that
these elements have non-trivial images. I am going to discuss possible approaches
to define a notion of an algebraic extension of *G*.
