关于有理椭圆曲面上有理点的稠密性

On the density of rational points on rational elliptic surfaces

Julie Desjardins

摘要:

设$\mathscr{E}\rightarrow\mathbb{P}^1_\mathbb{Q}$是以$\mathbb{P}^1_\mathbb{Q}$为基的$\mathbb{Q}$上的非平凡有理椭圆曲面。我们猜想任何非平凡的椭圆曲面都有$\mathbb{Q}$ -有理点的Zerkiki-稠密集.本文用几何和解析方法解决了$\mathscr{E}$是有理的情形下的猜想。首先,我们证明了对于$\mathscr{E}$有理,当$\mathscr{E}$是等平凡的且具有非零的$j$ -不变量时,以及当$\mathscr{E}$是非等平凡的且具有$II^*$,$III^*$,$IV^*$或$I^*_m$($m\geq0$)型纤维时,集合$\mathscr{E}(\mathbb{Q})$是Zerki-dense的。我们还使用奇偶猜想证明解析密度在某个家庭的isotrevivarious合理的椭圆曲面与$j=0$,并指定的情况下,我们的方法都不会导致我们的猜想的证明。

英文摘要:

Let $\mathscr{E}\rightarrow\mathbb{P}^1_\mathbb{Q}$ be a non-trivial rational elliptic surface over $\mathbb{Q}$ with base $\mathbb{P}^1_\mathbb{Q}$ (with a section). We conjecture that any non-trivial elliptic surface has a Zariski-dense set of $\mathbb{Q}$-rational points. In this paper we work on solving the conjecture in case $\mathscr{E}$ is rational by means of geometric and analytic methods. First, we show that for $\mathscr{E}$ rational, the set $\mathscr{E}(\mathbb{Q})$ is Zariski-dense when $\mathscr{E}$ is isotrivial with non-zero $j$-invariant and when $\mathscr{E}$ is non-isotrivial with a fiber of type $II^*$, $III^*$, $IV^*$ or $I^*_m$ ($m\geq0$). We also use the parity conjecture to prove analytically the density on a certain family of isotrivial rational elliptic surfaces with $j=0$, and specify cases for which neither of our methods leads to the proof of our conjecture.
