Stable ergodicity and Anosov flows

Authors: Keith Burns, Charles Pugh and Amie Wilkinson

Abstract:
We prove that the time-1 map of a C^2, volume-preserving Anosov flow on a compact 3-manifold, is stably ergodic if and only if the flow is not a (constant time) suspension of an Anosov diffeomorphism. In higher dimensions, we prove that the time one map is stably ergodic under the assumption that the strong stable and strong unstable foliations are not integrable.
