Topology Seminar - David Constantine
Title: Markov codings for geodesic flow on CAT(-1) spaces
Speaker: David Constantine, Wesleyan University
Abstract: In this talk I'll discuss some joint work with Jean-Francois Lafont and Dan Thompson constructing a strong Markov coding for the geodesic flow on a CAT(-1) space. This has a number of important dynamical consequences, but I'll focus on the geometric underpinnings of the result -- how the CAT(-1) curvature property makes the argument run. If time permits, I hope to discuss an application of this result to the co-amenability problem for isometry groups of CAT(-1) spaces. This application gives an alternate proof of a result of Coulon, Dal'Bo, and Sambusetti.
