Event description:
I’ll discuss how to leverage symbolic dynamics to understand Anosov diffeomorphisms of surfaces, starting with the most basic case of linear total automorphisms. The key idea is the construction of so-called Markov partitions that code the dynamics of the diffeomorphism.
More recently, the same ideas have been extended to prove new results about general diffeomorphisms of manifolds.
