Abstract: I will discuss joint work with Carel Faber, Soren Galatius, and Sam Payne in which we prove a formula, conjectured by Zagier in 2008, for the S_n-equivariant top-weight Euler characteristics of the moduli spaces of n-marked, genus g algebraic curves. Our techniques involve tropical geometry and graph complexes.
