数域扩张中的K次范

THE K-TIMES NORM OF THE ALGEBRAIC NUMBER FIELD EXTENSION

元素α的范与迹是数域扩张L/K中的两个基本概念。本文给出了数域扩张L/K中元素α的k次范的定义,它包含了文中范与迹这两个概念,同时给出了它的计算方法和相关的传递公式。

In this paper,k- times Norm of 2 in the algebraic number field extension was given. It contains the norm of a and the trace of a in the algebraic number field extension of reference [1],the method for calculation and proper results are drawn.
