Spectral methods: from surfaces to graphs and back (22/11/2017)

A number of methods from algebraic graph theory were influenced by the spectral theory of Riemann surfaces.  We pay it back, and take some classical results for graphs to the continuous setting. In particular, I will talk about colorings, average distance, and discrete random walks on surfaces. Based on joint works with E. DeCorte and A. Kamber.
