数域上加权射影空间上有理点的计数

Counting rational points on weighted projective spaces over number fields

Peter Bruin, Irati Manterola Ayala

摘要:

Deng(arXiv:math/9812082)给出了数域上加权射影空间上关于某一高度函数的有理点个数的一个渐近公式。我们证明了一个推广的邓的结果,涉及一个态射之间的加权射影空间,让我们来计算有理点的形象下,这个态射有界的高度。该方法为第一作者和Najman关于数域上具有指定水平结构的椭圆曲线的计数的一个结果提供了一个更一般、更简单的证明.我们还包括一些应用到模曲线的例子。

英文摘要:

Deng (arXiv:math/9812082) gave an asymptotic formula for the number of rational points on a weighted projective space over a number field with respect to a certain height function. We prove a generalization of Deng's result involving a morphism between weighted projective spaces, allowing us to count rational points whose image under this morphism has bounded height. This method provides a more general and simpler proof for a result of the first-named author and Najman on counting elliptic curves with prescribed level structures over number fields. We further include some examples of applications to modular curves.
