Technion Mathematics Colloquium
 
 TWO COLLOQUIUM TALKS ON MONDAY 3/1/2011.
 
See separate announcement for first talk at 15:30
 
Second talk
 
Technion Mathematics Special Colloquium
 
 Title: Productsets of large sets in amenable groups
 
Speaker: Alexander Fish (University of Wisconsin)

Time: Monday January 3 at 4:30 p.m. Amado 232 

Abstract
We will review recent developments in the study of products of sets of positive upper Banach density in countable
amenable groups. The methods are of dynamical origin and Kronecker factor of an apropriate ergodic ^-system (where
^ is the underlying amenable group) will play a crucial role. The talk is based on a joint work with M.Bjorklund
(ETH-Zurich).
 
 
Light refreshments will be served at 3:00 pm at the faculty lounge on the 8th floor.
