Title: Open sets of exponentially mixing Anosov flows

Speaker: Khadim War, IMPA and University of Chicago

Abstract: We prove that an Anosov flow with C^1 stable bundle mixes exponentially whenever the stable and unstable bundles are not jointly integrable. This allows us to show that if a flow is sufficiently close to a volume-preserving Anosov flow and dim(E^s) = 1, dim(E^u) ≥ 2 then the flow mixes exponentially whenever the stable and unstable bundles are not jointly integrable. This implies the existence of non-empty open sets of exponentially mixing Anosov flows. This is based on a joint work with Oliver Butterley.
