Title: Three sphere recognition modulo GRH 

Speaker: Neil Hoffman

Time: 3:30 PM 

Room: MSCS 509 

Abstract: In this largely expository talk, I will discuss the interplay between the Generalized Riemann Hypothesis and the problem of producing a relatively small sized certificate that a 3-manifold is not the three sphere.
