阿贝尔簇族的不可能交与多项式Pell方程

Unlikely Intersections in families of abelian varieties and the polynomial Pell equation

Fabrizio Barroero, Laura Capuano

摘要:

设S是定义在数域k上的光滑不可约曲线,考虑S上的阿贝尔概型A和A内的曲线C,两者都定义在k上。在以前的工作中,我们证明了:当A是椭圆型的纤维积时,如果C不包含在A的一个真子群方案中,则它至多包含1000个属于余维至少为2的平坦子群方案的点.在本文中,我们继续研究并解决了相对维数g大于或等于2的简单交换格式的幂的关键情形。这一结果与Habegger和Pila的上述结果和工作相结合,给出了一般阿贝尔概型的说明。这些结果在研究多项式几乎Pell方程的可解性方面有应用。

英文摘要:

Let S be a smooth irreducible curve defined over a number field k and consider an abelian scheme A over S and a curve C inside A, both defined over k. In previous works, we proved that when A is a fibered product of elliptic schemes, if C is not contained in a proper subgroup scheme of A, then it contains at most finitely many points that belong to a flat subgroup scheme of codimension at least 2. In this article, we continue our investigation and settle the crucial case of powers of simple abelian schemes of relative dimension g bigger or equal than 2. This, combined with the above mentioned result and work by Habegger and Pila, gives the statement for general abelian schemes. These results have applications in the study of solvability of almost-Pell equations in polynomials.
