摘要
给出了域上两个多项式作为多项式相等与作为多项式函数恒等的充要条件,引入有限域上约化多项式的概念,给出了有限域上多项式函数重根的定义及判定法则.
A sufficient and necessary condition of the uniformity of the equality as polynomials and polynomial functions are proposed.Moreover,the concept of reduced polynomial over a finite field is introduced to define the multiple root of polynomial function over a finite filed,and a criterion is given.
