Statistical stability for robust classes of maps with non-uniform expansion. (English) Zbl 1067.37034

The authors deal with properties of SRB measures. To this end, they consider open sets of transformations in a manifold \(\mathcal M\), exhibiting nonuniformly expanding behaviour in some invariant domain \(W\subset \mathcal M\). Under some suitable assumptions on each transformations the authors prove that the Sinai-Ruelle-Bowen (SRB) measure varies continuously with the dynamics in the \(L^1\) norm. The authors present a concrete application as well.
