Complete subvarieties of moduli spaces and the Prym map

Carel Faber, Gerard van der Geer

We prove that in characteristic p>0 the locus of stable curves of p-rank at most f is pure of codimension g-f in the moduli space of stable curves. Then we consider the Prym map an…

The order of the top Chern class of the Hodge bundle on the moduli space of abelian varieties

Torsten Ekedahl, Gerard van der Geer

We give upper and lower bounds for the order of the top Chern class of the Hodge bundle on the moduli space of principally polarized abelian varieties.
