“AN INTEGRABLE BILLIARD CLOSE TO AN ELLIPSE OF SMALL ECCENTRICITY IS AN ELLIPSE”

Abstract: In 1927 G. Birkhoff conjectured that if a billiard in a strictly convex smooth domain is integrable, the domain has to be an ellipse (or a circle). The conjecture is still wide open, and presents remarkable relations with open questions in inverse spectral theory and spectral rigidity. In the talk we show that a version of Birkhoff’s conjecture is true for small perturbations of ellipses of small eccentricity. This is joint work with A. Avila and V. Kaloshin

“On recent results of extreme value theory applied to dynamical systems”

Abstract:  We give a review of a few recent results of extreme value theory applied to random dynamical systems and to coupled lattice maps.

Our beloved biennal workshop, currently titled DinAmicI IV, Fourth Workshop of the Italian Dynamicists, will take place in Corinaldo from Monday the 22th through Thursday the 25th of June 2015.
