Ergodic Theory / Probability Seminar - Alena Erchenko
Title: Flexibility of Lyapunov exponents on the torus
Speaker: Alena Erchenko (Ohio State University)
Abstract: There are several interesting classes of measures. We will concentrate on the invariant measure that is absolutely continuous with respect to the Lebesgue measure and the measure of maximal entropy. We show that positive Lyapunov exponents with respect to these two probability measures for Anosov area-preserving diffeomorphisms on a two-torus that are homotopic to a fixed area-preserving Anosov automorphism take on all values that satisfy some well-known inequalities (work in progress).
