秩为1的模曲线和模形式的二次Chabauty

Quadratic Chabauty for modular curves and modular forms of rank one

Netan Dogra, Samuel Le Fourn

摘要:

在本文中,我们提供了二次Chabauty方法产生一个有限集的点的细化充分条件,与雅可比矩阵的秩的条件取代的条件的雅可比矩阵加上一个相关的Chow-Heegner点空间的商的秩。然后,我们应用这个条件证明了有限的这个集合的任何模曲线$X_{\mathrm{ns} }^+ (N)$和$X_0 ^+ (N)$亏格至少为2与N素数。证明依赖于存在商的雅可比矩阵的Mordell-Weil秩等于它的维数(至少为2),这是通过分析估计的消失阶的L-函数的模形式,感谢Kolyvagin-Logachev型结果。

英文摘要:

In this paper, we provide refined sufficient conditions for the quadratic Chabauty method to produce a finite set of points, with the conditions on the rank of the Jacobian replaced by conditions on the rank of a quotient of the Jacobian plus an associated space of Chow-Heegner points. We then apply this condition to prove the finiteness of this set for any modular curves $X_{\mathrm{ns} }^+ (N)$ and $X_0 ^+ (N)$ of genus at least 2 with N prime. The proof relies on the existence of a quotient of their Jacobians whose Mordell-Weil rank is equal to its dimension (and at least 2), which is proven via analytic estimates for orders of vanishing of L-functions of modular forms, thanks to a Kolyvagin-Logachev type result.
