在这篇文章中,我们将从一条曲线到环面簇的态射的个数的计算公式应用到三个不同的相关上下文中(前两个是在整体函数域上理解的):有界非正则高度有理点的Manin问题,有界高度的代数点的渐近性和曲线的某些模空间的不可约性,并应用于环面的Severi问题。
In this article, we apply counting formulas for the number of morphisms from a curve to a toric variety to three different though related contexts (the first two are to be understood over global function fields): Manin's problem for rational points of bounded non‐anticanonical height, asymptotics for algebraic points of bounded height and irreducibility of certain moduli spaces of curves, with application to the Severi problem for toric surfaces.
