曲线上有理点的$p$ -adic方法

A $p$-adic approach to rational points on curves

Bjorn Poonen

摘要:

1922年,莫德尔发表了一个惊人的声明,即对于一个多项式方程$f(x,y)=0$,如果复数解的拓扑结构足够复杂,那么有理数解的集合是有限的。这一点在1983年被法尔明斯证明,在1991年又被沃伊塔用不同的方法证明,但这两种证明都没有提供一种方法来证明所有的合理解,所以寻找其他证明的工作仍在继续。最近,劳伦斯和文卡特什发现了第三个证据,依赖于$p$ -adic伽罗瓦表示的家庭的变化;这是本博览会的主题。

英文摘要:

In 1922, Mordell conjectured the striking statement that for a polynomial equation $f(x,y)=0$, if the topology of the set of complex number solutions is complicated enough, then the set of rational number solutions is finite. This was proved by Faltings in 1983, and again by a different method by Vojta in 1991, but neither proof provided a way to provably find all the rational solutions, so the search for other proofs has continued. Recently, Lawrence and Venkatesh found a third proof, relying on variation in families of $p$-adic Galois representations; this is the subject of the present exposition.
