Maximal Eisenstein ideals and cuspidal subgroups of modular Jacobian varieties

Yuan Ren

In this paper, we study the torsion subgroup of $J_{0} (N)$ over the field generated by those points in the cuspidal group, where $N$ is an odd positive integer. We prove that, consid…

Quadratic torsion subgroups of modular Jacobian varieties

Yuan Ren

Let $D$ be an odd square-free positive integer and $C$ a divisor of $D$ . For any quadratic character $χ$ modulo $C$ , we prove that the $χ$ -part of the group $J_{0} (D C)_{tor}$ of…
