函数域上定度定高点的计数

Counting points of fixed degree and given height over function fields

Jeffrey Lin Thunder, Martin Widmer

摘要:

设$k$是函数域$\bfF_p(T)$的有限域扩张,$\bar{k}$是它的代数闭包.我们计算点在射影空间$\Bbb P ^{n-1}(\bar{k})$具有给定的高度和固定程度$d$在字段$k$。如果$n>2d+3$,我们推导出当高度趋于无穷大时它们的数量的渐近估计。作为一个应用,我们还推导出某些可分解形式的渐近估计。

英文摘要:

Let $k$ be a finite field extension of the function field $\bfF_p(T)$ and $\bar{k}$ its algebraic closure. We count points in projective space $\Bbb P ^{n-1}(\bar{k})$ with given height and of fixed degree $d$ over the field $k$. If $n>2d+3$ we derive an asymptotic estimate for their number as the height tends to infinity. As an application we also deduce asymptotic estimates for certain decomposable forms.
