Abstract

The aim of the project is to determine conditions that guarantee a system with weak forms of hyperbolicity (partially hyperbolic or non-uniformly hyperbolic) to have finitely many measures of maximal entropy. We state 8 projects, in a variety of contexts that include diffeomorphisms and flows, and propose approaches that use many tools, including Markov partitions, homoclinic classes and the specification property.
