Igor has spoken at the Princeton Topology Seminar last Thursday, November 18

Title: Somewhat simple curves on surfaces, and the mysteries of covering spaces.
Abstract: I will count some curves on 2-dimensional manifolds, and
will discuss some related issues in geometric (and otherwise) group
theory

Next Monday, November 29th, Igor is speaking at the Institute for Advanced Study Members Seminar

Title: (Some) Generic Properties of (Some) Infinite Groups

Abstract: This talk will be a biased survey of recent work on various properties of elements of infinite groups, which can be shown to hold with high probability once the elements are sampled from a large enough subset of the group (examples of groups: linear groups over the integers, free groups, hyperbolic groups, mapping class groups, automorphism groups of free groups . . . )
