高维阿贝尔簇族中的扭点与跳高

Torsion points and height jumping in higher-dimensional families of abelian varieties

David Holmes

摘要:

在1983年西尔弗曼和泰特表明,一组点在一个1维家庭的阿贝尔簇的一节无限秩序有“小高度”是有限的。我们猜想一个推广到高维的家庭,在那里我们取代“有限”的“不Zagliki密集”。我们证明了这个猜想蕴含着阿贝尔簇上扭点的一致有界性猜想。然后,我们证明了这个新猜想的几个特殊情况。

英文摘要:

In 1983 Silverman and Tate showed that the set of points in a 1-dimensional family of abelian varieties where a section of infinite order has `small height' is finite. We conjecture a generalisation to higher-dimensional families, where we replace `finite' by `not Zariski dense'. We show that this conjecture would imply the Uniform Boundedness Conjecture for torsion points on abelian varieties. We then prove a few special cases of this new conjecture.
