Event description:
The first general, robust mechanism for ergodicity was developed by E. Hopf in the 1930’s in the context of Riemannian geometry. Loosely put, Hopf showed that for a negatively curved, compact surface, the “typical infinite geodesic fills the manifold in a very uniform way, a property called equidistribution. I will discuss Hopf’s basic idea in both topological and measure-theoretic settings and how it has developed into a widely applicable mechanism for chaotic behavior in smooth dynamics.
