TRHW01 - Workshop on topology, representation theory and higher structures

I will give an introduction to Kontsevich’s graph complexes and explain how they are related to various spaces of graphs and to automorphism groups of free groups and surface groups.  In the second hour I will discuss recent results on the Euler characteristic  of various graph complexes.
