摘要:

我们计算了模曲线$\mathcal{X}_0(N)$的积分模型乘积上Hecke对应的算术交,并将其与某些Siegel Eisenstein级数的导数联系起来,当$N$为奇数且无平方因子时。我们通过建立与$\mathcal{X}_0(N)^{2}$相关的Rapoport--Zink空间上的算术交数与二次型局部表示密度的导数之间的精确恒等式来证明这一点。

英文摘要:

We compute the arithmetic intersections of Hecke correspondences on the product of integral model of modular curve $\mathcal{X}_0(N)$ and relate it to the derivatives of certain Siegel Eisenstein series when $N$ is odd and squarefree. We prove this by establishing a precise identity between the arithmetic intersection numbers on the Rapoport--Zink space associated to $\mathcal{X}_0(N)^{2}$ and the derivatives of local representation densities of quadratic forms.
