Title:Growth Rate of Periodic orbits for Geodesic Flows on Surfaces with Regions of Positive Curvature
Seminar:Working Seminar: Dynamics and its Working Tools
Speaker:Bryce Weaver
Abstract:
We construct a Margulis measure on the unit tangent bundle of compact surfaces that have negative curvature outside of focusing caps. This measure is then used to obtain a lower bound Cesaro estimate that gives exponential growth of the number periodic orbits for the geodesic flow.
