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).
