AGR Seminar -- The Cohen-Lenstra heuristics: from arithmetic to topology and back again

Host venue
University of Western Australia

Abstract

I will discuss some models of what a ?random abelian group? is, and some conjectures (the Cohen-Lenstra 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?).
