有限域上多项式值集的概率方法

A probabilistic approach to value sets of polynomials over finite fields

Zhicheng Gao, Qiang Wang

摘要:

本文研究有限域$\mathbb{F}_q$上次数至多为$q-1$的随机多项式的值集大小的分布。我们得到了精确的概率分布,并表明,缺失值的数量趋于正态分布的$q$走向无穷大。通过对随机$r$ -阶分圆映射的研究,得到了这些结果.一些随机集的工会的大小的变化也被认为是。

英文摘要:

In this paper we study the distribution of the size of the value set for a random polynomial with degree at most $q-1$ over a finite field $\mathbb{F}_q$. We obtain the exact probability distribution and show that the number of missing values tends to a normal distribution as $q$ goes to infinity. We obtain these results through a study of a random $r$-th order cyclotomic mappings. A variation on the size of the union of some random sets is also considered.
