Abstract

We show that within a C1C^1-neighbourhood U\mathcal{U} of the set of volume preserving Anosov diffeomorphisms on the three-torus T3\mathbb{T}^3 which are strongly partially hyperbolic with expanding center, any fUDiff2(T3)f\in\mathcal{U}\cap\operatorname{Diff}^2(\mathbb{T}^3) satisfies the dichotomy: either the strong stable and unstable bundles EsE^s and EuE^u of ff are jointly integrable, or any fully supported uu-Gibbs measure of ff is SRB.
