In all available papers, on power integral bases of any pure sextic number fields K generated by α a complex root of a monic irreducible polynomial f(x)=x6mZ[x], it was assumed that the rational integer m1 is square free. In this paper, we investigate the monogeneity of any pure sextic number field, where the condition m is a square free rational integer is omitted. We start by calculating an integral basis of ZK; the ring of integers of K. In particular, we characterize when ZK=Z[α], that is when ZK is monogenic and generated by α. We give sufficient conditions on m, which warranty that K is not monogenic. We finish the paper by investigating the case, where m=e5 and e1 is a square free rational integer.

具有非平方自由系数的纯六性数域的整数基和单性

在所有可用的论文中,在由α生成的任何纯正弦数场K的幂积分基础上,它是一元不可约多项式的复数根FX=X6-ž[X],假设有理整数 1个没有正方形。在本文中,我们研究了任何纯正六边形字段的均一性,其中条件m是一个正方形,但省略了有理整数。我们首先计算žķ; K的整数环。特别是,我们描述了什么时候žķ=ž[α],那是什么时候 žķ是单基因的,由α生成。我们对m给出足够的条件,该条件保证K不是单基因的。我们通过调查此案来完成本文,其中=Ë5Ë1个 是一个平方自由有理整数。
