Research Seminar: Compact subvarieties of $\mathcal A_g$

The aim of the seminar is to discuss recent results by Grushevsky, Mondello, Salvati Manni and Tsimerman, where the maximal dimension of a compact subvariety of the moduli space of complex principally polarized abelian varieties of dimension $g$ is determined.

Date and place: Thursday, 2-4pm, N-U-3.05. First meeting: October 10.
