Abstract : In this talk, we consider the moduli space of principally polarized abelian varieties of dimension g in positive characteristic. This space carries a family of vector bundles parameterized by a free Z-module of rank g. We study which of these vector bundles admit nonzero global sections, by linking this problem to representation theory of reductive groups.
