Hwajong Yoo

摘要:

设$\mathcal{C}_N$是无平方整数$N>6$的雅可比矩阵$J_0(N)$的尖点子群。对水平$N$的Hecke环的任一Eisenstein极大理想$\mathfrak{m}$,证明了$\mathcal{C}_N[\mathfrak{m}]\neq 0$ .为了证明这一点,我们计算指数的爱森斯坦理想$\mathcal{I}$包含在$\mathfrak{m}$通过计算的阶的尖形因子消灭$\mathcal{I}$。

英文摘要:

Let $\mathcal{C}_N$ be the cuspidal subgroup of the Jacobian $J_0(N)$ for a square-free integer $N>6$. For any Eisenstein maximal ideal $\mathfrak{m}$ of the Hecke ring of level $N$, we show that $\mathcal{C}_N[\mathfrak{m}]\neq 0$. To prove this, we calculate the index of an Eisenstein ideal $\mathcal{I}$ contained in $\mathfrak{m}$ by computing the order of a cuspidal divisor annihilated by $\mathcal{I}$.
