曲面的Chabauty-Coleman界

A Chabauty-Coleman bound for surfaces

Jerson Caro, Hector Pasten

摘要:

建立在工作的Chabauty从1941年,科尔曼证明了在1985年明确的界限,一些合理的点的曲线$C$属$g\ge 2$定义的一些领域$F$,雅可比的秩最多$g-1$。也就是说,在$F=\mathbb{Q}$的情况下,如果$p>2g$是好约化的素数,则$C$的有理点数至多是$\mathbb{F}_p$ -点数加上来自$C$的规范类的贡献。我们证明了一个结果类似于科尔曼的情况下,双曲曲面$X$在数域上,嵌入在一个阿贝尔品种$A$的秩最多为1,在适当的条件下,在辅助素数的减少类型。这提供了第一次延伸科尔曼的明确界限以外的情况下,曲线。本文的主要创新之处是利用正特征超定微分方程组研究了$p$ -adic解析子群与$A$子簇的交.

英文摘要:

Building on work by Chabauty from 1941, Coleman proved in 1985 an explicit bound for the number of rational points of a curve $C$ of genus $g\ge 2$ defined over a number field $F$, with Jacobian of rank at most $g-1$. Namely, in the case $F=\mathbb{Q}$, if $p>2g$ is a prime of good reduction, then the number of rational points of $C$ is at most the number of $\mathbb{F}_p$-points plus a contribution coming from the canonical class of $C$. We prove a result analogous to Coleman's bound in the case of a hyperbolic surface $X$ over a number field, embedded in an abelian variety $A$ of rank at most one, under suitable conditions on the reduction type at the auxiliary prime. This provides the first extension of Coleman's explicit bound beyond the case of curves. The main innovation in our approach is a new method to study the intersection of a $p$-adic analytic subgroup with a subvariety of $A$ by means of overdetermined systems of differential equations in positive characteristic.
