Title: Linear programming techniques in two-dimensional hyperbolic geometry

Abstract: After a reminder on the geometry of hyperbolic surfaces, I will talk about a joint project with Maxime Fortier Bourque. In this project, we use ideas coming from the theory of sphere packings, due to Cohn-Elkies and Gorbachev, in order to prove new bounds on geometric and spectral invariants associated to hyperbolic surfaces.
