显模混合椭圆Chabauty-Kim

Explicit Motivic Mixed Elliptic Chabauty-Kim

David Corwin

摘要:

本文的主要观点是将Dan-Cohen-Wewers和Dan-Cohen等人的论文中提出的显式动力学Chabauty-Kim方法推广到非有理曲线上。特别地,我们计算了穿孔椭圆曲线上$\mathbb{Z}[1/\ell]$ -点的Chabauty-Kim理想的元素的抽象形式,为某些高亏格曲线的构造奠定了基础.为此,我们开发了一个“显式Tannakian Chabauty-Kim方法”使用$\mathbb{Q}_{p}$ -Tannakian类别的伽罗瓦表示的地方$\mathbb{Q}$ -线性动机。在未来的工作中,我们打算使用这种方法来明确地应用Chabauty-Kim方法的曲线的正亏格的情况下,二次Chabauty不适用。

英文摘要:

The main point of the paper is to take the explicit motivic Chabauty-Kim method developed in papers of Dan-Cohen--Wewers and Dan-Cohen and the author and make it work for non-rational curves. In particular, we calculate the abstract form of an element of the Chabauty-Kim ideal for $\mathbb{Z}[1/\ell]$-points on a punctured elliptic curve, and lay some groundwork for certain kinds of higher genus curves. For this purpose, we develop an "explicit Tannakian Chabauty-Kim method" using $\mathbb{Q}_{p}$-Tannakian categories of Galois representations in place of $\mathbb{Q}$-linear motives. In future work, we intend to use this method to explicitly apply the Chabauty-Kim method to a curve of positive genus in a situation where Quadratic Chabauty does not apply.
