| Aug 31, 2017 at 10:22 | comment | added | Ariyan Javanpeykar | There are infinitely many pairwise non-isomorphic supersingular abelian surfaces over $\overline{\mathbb{F}_p}$. (You even have a family parametrized by $\mathbb P^1$, but peu importe.) Is the Torelli map $\mathcal{M}_2\to \mathcal{A}_2$ surjective? Is the pull-back of the supersingular locus (contained in) the supersingular locus of $\mathcal{M}_2$? | |
