Local maxima of the systole function

Abstract: The systole of a hyperbolic surface is the length of its shortest closed geodesic(s). Schmutz Schaller initiated the study of the systole function and its local maxima in the 90's. I will explain a construction of a new infinite family of closed hyperbolic surfaces which are local maxima for the systole. The simplest of these surfaces is the Bolza surface, which is the surface of genus 2 with the largest number of symmetries. In higher genus, we obtain super-exponentially many examples and most of them have a trivial automorphism group. This is joint work with Kasra Rafi.

On totally geodesic subvarieties of moduli spaces

Abstract: We will show that holomorphic isometries between Teichmüller spaces of closed Riemann surfaces in their Teichmüller metrics are geometric. That is, they are obtained from covering constructions of the underlying surfaces. We will also discuss recent progress on the study of real and complex totally geodesic submanifolds of Teichmüller and moduli spaces in dimensions two or more.
