Mathematics Seminar Series: Groups, Geometry, and Topology

Abstract: Quasigeodesic and pseudo-Anosov flows are defined by simple geometric conditions and interact in surprising ways with the geometry of 3-manifolds. I will discuss recent work with Michael Landry on this interaction, including the resolution of Calegari’s Flow Conjecture, that every quasigeodesic flow on a closed hyperbolic 3-manifold may be deformed into a flow that is both quasigeodesic and pseudo-Anosov.
