Dear All, two Dynamical Systems online seminars from ICTP this week:

Dominic Veconi (Penn State University)
Tuesday 30 June 2020, 16:00 – 17:00
Title: Ergodic and thermodynamic properties of pseudo-Anosov diffeomorphisms
by Dominic Veconi (Penn State University) as part of ICTP Math Seminar

Abstract
Abstract: We discuss the thermodynamic and ergodic properties of a  
smooth realization of pseudo-Anosov surface homeomorphisms. In this  
realization, pseudo-Anosov map is uniformly hyperbolic outside of a  
neighborhood of a set of singularities, and the trajectories are  
slowed down so the differential is the identity at the singularities.  
Using Young towers, we prove existence and uniqueness of equilibrium  
measures for geometric $t$-potentials. This family of equilibrium  
measures includes a unique smooth SRB measure and a measure of maximal  
entropy, the latter of which has exponential decay of correlations and  
the Central Limit Theorem.

Title: Math Associates Seminar: Closed geodesics on surfaces without  
conjugate points
by Khadim War (IMPA/University of Chicago) as part of ICTP Math Seminar

Abstract
Abstract: We obtain Margulis-type asymptotic estimates for the number  
of free homotopy classes of closed geodesics on certain manifolds  
without conjugate points. Our results cover all compact surfaces of  
genus at least 2 without conjugate points. This is based on a join  
work with Vaughn Climenhaga and Gerhard Knieper.
