Tel Aviv University
Hello everyone,
The next colloquium talk will be held on Monday, 30/1/2012, 12:15, Schreiber
006, Tel Aviv University. The speaker is
    Yehuda Shalom (Tel Aviv University and UCLA)
and the title of his talk is
    Some recent developments related to Gromov's polynomial growth theorem
The abstract is given below. Tea and coffee at 12:00, same room.
Hope to see you there. For information about future colloqiua, see
You are all welcome to suggest colloquium speakers for the second semester.
Abstract: Gromov's celebrated theorem asserts that given a group G generated
by a finite set S, if the number of elements which are a product of at
most n elements of S is bounded by a fixed polynomial in n then G has a
index nilpotent subgroup. In the talk we shall describe some far reaching
developments of the last 5 years surrounding this result. Among these
is a very surprising path linking deep theorems of two retired members
of the department (Freiman, Hirshfeld) originating in very different
areas of research (harmonic analysis, logic).
