Abstract
We prove that generically in \({\text {Diff}}^{1}_{m}(M)\), if an expanding f-invariant foliation W of dimension u is minimal and there is a periodic point of unstable index u, the foliation is stably minimal. By this we mean there is a \(C^{1}\)-neighborhood \({\mathcal {U}}\) of f such that for all \(C^{2}\)-diffeomorphisms \(g\in {\mathcal {U}}\), the g-invariant continuation of W is minimal. In particular, all such g are topologically mixing. Moreover, all such g have a hyperbolic ergodic component of the volume measure m which is essentially dense. This component is, in fact, Bernoulli. We provide new examples of diffeomorphisms with stably minimal expanding foliations which are not partially hyperbolic.
