Title: Gibbs measures (II)

Abstract: In this week we will continue our discussion on Gibbs measure. We will focus on the symbolic dynamics systems and introduce Ruelle’s Perron-Frobenius theorem. Our discussion will based on Rufus Bowen’s “ Equilibrium States and the Ergodic Theory of Anosov Diffeomorphisms” and well as “ Zeta Function and the Periodic orbits structure of hyperbolic dynamics” written by William Parry and Mark Pollicott.
