有限域中关联问题的初等方法

Elementary methods for incidence problems in finite fields

Javier Cilleruelo, Alex Iosevich, Ben Lund, Oliver Roche-Newton, Misha Rudnev

摘要:

本文用初等方法证明了$\mathbb{F}_q^n$中点与球面的一个关联定理。作为一个应用,我们证明了$P\subset \mathbb{F}_q^2$的任何点集与$|P|\geq 5q$确定所有圆的正比例.后者的结果是一个类似的贝克定理的圆圈是最佳的乘法常数。

英文摘要:

We use elementary methods to prove an incidence theorem for points and spheres in $\mathbb{F}_q^n$. As an application, we show that any point set of $P\subset \mathbb{F}_q^2$ with $|P|\geq 5q$ determines a positive proportion of all circles. The latter result is an analogue of Beck's Theorem for circles which is optimal up to multiplicative constants.
