函数域上具有差错率的等分布与丢番图逼近

Equidistribution with an error rate and Diophantine approximation over function fields

Sanghoon Kwon, Seonhee Lim

摘要:

本文证明了函数域$\mathbf{K}$上准球面群的某个真子群$H$在$SL(d,\mathbf{K})/SL(d,\mathbf{Z})$中的每个$H$ -轨道具有差错率的点态等分布,推广了Kleinbock-Shi-Weiss的工作.此外,我们还得到了带权丢番图不等式积分解个数的一个渐近公式,推广了Dodson-Kristensen-Levesley的一个结果.这一结果使我们能够证明$C_α$类无界函数的点态等分布,这类无界函数是Eskin-Margulis-Mozes首先提出的。

英文摘要:

We prove pointwise equidistribution with an error rate of each $H$-orbit in $SL(d,\mathbf{K})/SL(d,\mathbf{Z})$ for a certain proper subgroup $H$ of horospherical group over a function field $\mathbf{K}$, extending a work of Kleinbock-Shi-Weiss. Moreover, we obtain an asymptotic formula for the number of integral solutions to the Diophantine inequalities with weights, generalizing a result of Dodson-Kristensen-Levesley. This result enables us to show pointwise equidistribution for unbounded functions of class $C_α$, which was first introduced by Eskin-Margulis-Mozes.
