阿贝尔簇的子群逼近

Approximation on abelian varieties by its subgroups

Arash Rastegar

摘要:

本文利用数域上Faltings-Wustholz观测的一个改进,给出了阿贝尔簇上丢番图逼近的Faltings定理的代数几何表述.事实上,我们证明了:对于阿贝尔簇A的任何几何不可约子簇E和A(C)的任何生成子群F,我们对某个常数c有形式d_v(E;x)>cH(x)^d的估计,其中d_v(E;x)表示F中一点x在E外的距离,v是K的一个位置。这是证明之前,只有F是一个数字域上的有理点的集合。

英文摘要:

In this paper, we introduce an algebro-geometric formulation for Faltings' theorem on diophantine approximation on abelian varieties using an improvement of Faltings-Wustholz observation over number fields. In fact, we prove that, for any geometrically irreducible sub-variety E of an abelian variety A and any finitely generated subgroup F of A(C) we have an estimate of the form d_v(E;x) >cH(x)^d for for some constant c where d_v(E;x) denotes the distance of a point x in F outside E and v is a place of K. This was proved before, only for F being the set of rational points of A over a number field.
