On mostly expanding diffeomorphisms

Dynamical Systems 2016-11-23 v2

Abstract

In this work we study the class of mostly expanding partially hyperbolic diffeomorphisms. We prove that such class is CrC^r-open, r>1r>1, among the partially hyperbolic diffeomorphisms (in the narrow sense) and we prove that the mostly expanding condition guarantee the existence of physical measures and provide more information about the statistics of the system. Ma\~n\'e's classical derived-from-Anosov diffeomorphism on T3\mathbb{T}^3 belongs to this set.
