关于有限域可加特征标的一个注记

A note on additive characters of finite fields

Lucas Reis

摘要:

令$\mathbb F_q$是具有$q$元素的有限域,其中$q$是素数幂,对于每个整数$n\ge 1$,令$\mathbb F_{q^n}$是$\mathbb F_q$的唯一$n$ -度扩张. $\mathbb F_{q^n}$中元素的$\mathbb F_q$ -阶和$\mathbb F_{q^n}$上的加性特征标已广泛用于有限域上存在性结果的证明(例如,原始正规基定理)。在本说明中,我们提供了这两个对象之间的有趣关系。

英文摘要:

Let $\mathbb F_q$ be the finite field with $q$ elements, where $q$ is a prime power and, for each integer $n\ge 1$, let $\mathbb F_{q^n}$ be the unique $n$-degree extension of $\mathbb F_q$. The $\mathbb F_q$-orders of an element in $\mathbb F_{q^n}$ and an additive character over $\mathbb F_{q^n}$ have been extensively used in the proof of existence results over finite fields (e.g., the Primitive Normal Basis Theorem). In this note we provide an interesting relation between these two objects.
