Topology of moduli spaces of tropical curves
Sam Payne, Mathematics Department, Yale University,

The top weight cohomology of the moduli space of algebraic curves is naturally identified (with a degree shift) with the reduced rational homology of a moduli space of stable tropical curves. I will discuss the structure of this tropical moduli space and applications to computing new cohomology classes on M_g, based on recent joint work with M. Chan and S. Galatius.
