"Diophantine geometry over groups and the elementary theory of a free group"

** Abstract: **
We study the structure of sets of solutions to systems of
equations over a free group, projections of such sets, and the
structure of elementary sets defined over a free group. The
structure theory we obtain enable us to answer some questions
of A. Tarski, and classify those finitely generated groups
that are elementary equivalent to a free group.

Coffee, Cookies at the faculty lounge at 3:30.
