Abstract:

A precise and testable modularity conjecture for rational abelian surfaces $A$ with trivial endomorphisms, $\mathrm {End}_{\mathbb {Q}} A = \mathbb {Z}$, is presented. It is consistent with our examples, our non-existence results and recent work of C. Poor and D. S. Yuen on weight 2 Siegel paramodular forms. We obtain fairly precise information on $\ell$-division fields of semistable abelian varieties, mainly when $A[\ell ]$ is reducible, by considering extension problems for group schemes of small rank.
