仿射曲线上有界次数的整点

Integral points of bounded degree on affine curves

Aaron Levin

摘要:

将Siegel关于仿射曲线上积分点的定理推广到有界次数的积分点,给出了数域上具有无穷多个d次以下积分点的仿射曲线的一个完整刻画.推广Picard定理,我们证明了一个类似的结果,它刻画了复仿射曲线在$\mathbb{C}$的d次(或更少)解析覆盖上具有一个非常数全纯映射.

英文摘要:

We generalize Siegel's theorem on integral points on affine curves to integral points of bounded degree, giving a complete characterization of affine curves with infinitely many integral points of degree d or less over some number field. Generalizing Picard's theorem, we prove an analogous result characterizing complex affine curves admitting a nonconstant holomorphic map from a degree d (or less) analytic cover of $\mathbb{C}$.
