Adrien Sauvaget (UU) - Counting geodesics on flat surfaces
Description:We will present a universal formula for the growth rate of geodesics between
two conical singularities of a flat surface. The proof of this formula involves
both ingredients from representation theory via the Bloch-Okounkov formalism
and from intersection theory on moduli spaces.

Hana Kourimska (TU Berlin) - A discrete uniformization theorem
The uniformization theorem, posed at the beginning of the 1880's, states that every oriented two-dimensional Riemannian manifold M is conformally equivalent to a Riemannian manifold N with constant Gaussian curvature. Given any such M, the Riemannian metric on N can be found by letting M evolve under the two-dimensional Ricci flow. In my talk I will show the equivalent result for a discretization of this theorem: instead of a smooth surface I start with a piecewise flat surface -- a surface which is isometric to a plane everywhere but in a finite amount of cone-like singularities. I introduce a discretized version of all the ingredients -- the metric, conformal equivalence and Gaussian curvature -- and explain why these are reasonable approximations of their smooth counterparts. After stating the discrete uniformization theorem using these notions I prove it by translating the setting into the realm of hyperbolic geometry.
