Title: Partial hyperbolicity and foliations in 3-manifolds
Speaker: Rafael Potrie - CMAT (Uruguay)
Abstract: I'll explain a beautiful old result by Margulis and Plante-Thurston stating that if a 3-manifold admits an Anosov flow then its fundamental group has exponential growth (as well as explaining what these things mean). I will then explain how some ideas can be pushed further to understand the topological structure of partially hyperbolic diffeomorphisms.
