We introduce the property with no relation to the expansion of number field,then we put emphasis on problems with relation to number field.
首先介绍了高等代数中与数域的扩张无关的性质,然后重点讨论了与数域有关的问题,特别是线性空间与数域的关系问题,并给出了有关结论。
ln this paper we prove that if θ is a transcendental number,then the fractional set S(θ;m,n) is not a number field.
本文证明了 :如果θ是超越数 ,则分式集S(θ;m ,n)不是数
we give three definitions of linearly dependency of system of vectors on the basis of common definition, and prove that two theorems for relations of linearly dependency of system of vectors with number fields.
在不少的高等代数和线性代数教材中，关于向量线性相关性的定义常不涉及数域。
In this paper, we summarize the foundations of Algebraic function fields, algebraic curves over finite fields and algebraic geometry codes, then we focus on the dimensions of codes on the quotient of the hermitian curves, by using the theory of weierstrass semigroup and the idea of Ho.
我们在系统地总结了代数函数域,有限域上的代数曲线和代数几何码的基本知识的基础上,利用Weierstrass子半群理论,使用Homma和Kim的方法,讨论了Hermite曲线商域上码的维数问题,得到的主要结果如下:1。
g′) denotes the genus of the algebraic function field K(resp.
首先计算出了代数闭域上的有理函数域的位的次数,然后利用代数函数域的Kummer扩张的亏格关系,给出了具体计算形如C∶yn=(x-a1)n1(x-a2)n2…(x-as)ns的曲线的亏格公式。
