Anomalous partially hyperbolic diffeomorphisms II: stably ergodic examples

Dynamical Systems 2016-12-21 v2 Geometric Topology

Abstract

We construct examples of robustly transitive and stably ergodic partially hyperbolic diffeomorphisms ff on compact 33-manifolds with fundamental groups of exponential growth such that fnf^n is not homotopic to identity for all n>0n>0. These provide counterexamples to a classification conjecture of Pujals.
