Counting points on $\text{Hilb}^m\mathbb{P}^2$ over function fields

Adelina Mânzăţeanu

摘要:

设$K$是一个具有正特征的全局域。本文给出了Hilbert格式$\text{Hilb}^2\mathbb{P}^2$上有界高度$K$ -点个数的渐近公式,并证明了在函数场设置下,通过消除例外的薄集,主项前的常数与Peyre的预言一致.此外,我们将有限域上的$V$簇上的整数与$0$-圈的类比推广到$K$上的$V$簇上的$0$ -圈,并建立了当$V = \mathbb{P}^2$ .

英文摘要:

Let $K$ be a global field of positive characteristic. We give an asymptotic formula for the number of $K$-points of bounded height on the Hilbert scheme $\text{Hilb}^2\mathbb{P}^2$ and show that by eliminating an exceptional thin set, the constant in front of the main term agrees with the prediction of Peyre in the function field setting. Moreover, we extend the analogy between the integers and $0$-cycles on a variety $V$ over a finite field to $0$-cycles on a variety $V$ over $K$ and establish a version of the prime number theorem in the case when $V = \mathbb{P}^2$.
