Event description:

I will give a hopefully accessible introduction to some work on

tropical moduli spaces of curves and abelian varieties. I will report

on joint work with Madeline Brandt, Juliette Bruce, Margarida Melo,

Gwyneth Moreland, and Corey Wolfe, in which we find new rational

cohomology classes in the moduli space A_g of abelian varieties using

tropical techniques. And I will try to touch on a new point of view on

this topic, namely that of differential forms on tropical moduli

spaces, following the work of Francis Brown.
