Title: Profinite rigidity of some fibered, hyperbolic 3-manifold groups

Speaker: Tam Cheetham-West (Rice University)

Abstract: For an infinite, residually finite group, it is interesting to ask what properties of the group are captured by its finite quotients. We will discuss how to use ideas of Bridson-McReynolds-Reid-Spitler to show, for example, that the fundamental group of zero surgery on the knot 6_2 is completely determined (among all residually finite groups) by the collection of its finite quotients.
