| Jan 16, 2016 at 14:19 | comment | added | Jason Starr | I just want to clarify the question. There exists a finite, closed subgroup scheme $\Gamma \subset \text{Prym}(C/C')$ and a flat morphism of group schemes $\pi:J(C)\to \text{Prym}(C/C')/\Gamma$ that restricts to the quotient morphism $q:\text{Prym}(C/C')\to\text{Prym}(C/C')/\Gamma$. Certainly the composition of $\pi$ with the Abel map $\text{sym}^d(C)\to J(C)$ is surjective. Are you asking whether this surjection factors through $q$? | |
