On the number of zeros to the equation $f (x_{1}) + ... + f (x_{n}) = a$ over finite fields

Chaoxi Zhu, Yulu Feng, Shaofang Hong +1

Let $p$ be a prime, $k$ a positive integer and let $F_{q}$ be the finite field of $q = p^{k}$ elements. Let $f (x)$ be a polynomial over $F_{q}$ and $a \in F_{q}$ . We d…

Sums of polynomial-type exceptional units modulo $n$

Junyong Zhao, Shaofang Hong, Chaoxi Zhu

Let $f (x) \in Z [x]$ be a nonconstant polynomial. Let $n, k$ and $c$ be integers such that $n \geq 1$ and $k \geq 2$ . An integer $a$ is called an $f$ -exunit in the ring $\mathbb{…

A certain reciprocal power sum is never an integer

Junyong Zhao, Shaofang Hong, Xiao Jiang

By $(Z^{+})^{\infty}$ we denote the set of all the infinite sequences $S = {s_{i}}_{i = 1}^{\infty}$ of positive integers (note that all the $s_{i}$ are not necessarily…

Counting rational points of an algebraic variety over finite fields

Shuangnian Hu, Shaofang Hong, Xiaoer Qin

Let $F_{q}$ denote the finite field of odd characteristic $p$ with $q$ elements ( $q = p^{n}, n \in N$ ) and $F_{q}^{*}$ represent the nonzero elements of $\mathbb{…
