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 <http://www.math.tau.ac.il/~klartagb/colloq_2011.html> You are all welcome to suggest colloquium speakers for the second semester. Yours, Bo'az ------------- 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 finite 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). --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: <klartagb@post.tau.ac.il>
