Wilson's Theorem states that the product of all nonzero elements of a finite field Fq is −1. In this article, we define some natural subsets SFq× (q odd) and find formulas for the product of the elements of S, denoted ∏S. These new formulas are appealing for the simple, natural description of the sets S, and for the simplicity of the product. An example is {aFq×:1a and 3+a are nonsquares}=2 if q±1(mod12), or −1 otherwise.

Dickson多项式产生的新的类似Wilson的定理

威尔逊定理指出,有限域的所有非零元素的乘积 Fq是-1。在本文中,我们定义了一些自然子集小号Fq×q奇)和找到的元件的产品配方小号,表示为Π小号。这些新公式吸引了集合S的简单,自然的描述,并简化了产品。一个例子是{一种Fq×1个-一种 和 3+一种 是非正方形}=2 如果 q±1个12,否则为-1。
