模雅可比簇的二次扭子群

Quadratic torsion subgroups of modular Jacobian varieties

Yuan Ren

摘要:

设$D$是一个无奇平方的正整数,$C$是$D$的除数。对于任何二次特征标$χ$模$C$,我们证明了$J_0(DC)$的扭点群$J_0(DC)_\text{tor}$的$χ$ -部分与其尖子群的$χ$ -部分重合,远离那些坏约化的素数或旧形式和新形式之间可能发生的同余.

英文摘要:

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 $J_0(DC)_\text{tor}$ of torsion points of $J_0(DC)$ coincides with the $χ$-part of its cuspidal subgroup, away from those primes of bad reduction or where possible congruences between oldforms and newforms occur.
