 AMSI ACCESS GRID SEMINAR
 Speaker: Akshay Venkatesh, Stanford University
 Title: The CohenLenstra heuristics: from arithmetic to topology and back again
 Location: Room V206, Mathematics Building (Callaghan Campus) The University of Newcastle
 Access Grid Venue: TBC
 Time and Date: 1:00 pm, Wed, 25^{th} Sep 2013
 Abstract:
I will discuss some models of what a "random abelian group" is, and some conjectures (the CohenLenstra heuristics of the title) about how they show up in number theory. I'll then discuss the function field setting and a proof of these heuristics, with Ellenberg and Westerland. The proof is an example of a link between analytic number theory and certain classes of results in algebraic topology ("homological stability").
