I will give a talk on my joint result with Sylvain Crovisier and Omri Sarig about Viana’s conjecture for smooth surface diffeomorphisms. In this work we deduce the conjecture by using the techniques of our paper on the continuity properties of Lyapunov exponents. This was prompted by David Burguet preprints.

The conference is scheduled August 26-30th, will include 26 talks on dynamics systems and especially smooth ergodic theory. The announcement is here.

Our work (with Sylvain Crovisier and Omri Sarig) on the continuity property of Lyapunov exponents of surface diffeomorphisms has now been published online at Inventiones: along sequences of ergodic probability measures that converge weak-* and in entropy to a limiting measure, the exponents also converge.

This has nice consequences for Sinai-Ruelle-Bowen measures (see especially this latter work). It will lead to stronger ergodic properties for the measures of maximal entropy through a new notion of *Strongly Positive Recurrent diffeomorphisms* (work in progress, also with S. Crovisier and O. Sarig).
