Title: Area preserving diffeomorphisms with polynomial decay of correlations
Speaker: Farruh Shahidi (Pennsylvania State University)
Abstract: We show that any surface admits an area preservingdiffeomorphism with non-zero Lyapunov exponents which is Bernoulli and has polynomial decay of correlations. We establish both upper and lower polynomial bounds on correlations (joint work with Ya. Pesin and S.Senti).
