Title. Robust minimality of strong foliations for DA diffeomorphisms:  new examples


Let f be a C^2 partially hyperbolic diffeomorphisms of T^3 (not necessarily volume preserving or transitive) isotopic to a linear Anosov diffeomorphism A with eigenvalues k_3<1<k_2<k_1. If the set
\{x: \mid \log \det(Tf\mid_{E^{cu}(f)})\mid \leq \log k_1 \} has zero volume inside any unstable leaf of f, then the stable foliation of f is C^1 robustly minimal, i.e., the stable foliation of any diffeomorphism C^1 sufficiently close to f is minimal. In particular, f itself is robustly transitive.
We build, with this criterion, a new example of a C^1 open set of DA diffeomorphisms, such that the strong stable foliation and the strong unstable foliation of any diffeomorphism in this open set are both minimal. The existence of such an example was unknown in this setting. This is a joint work with  R. Ures and J. Yang.
