Abstract

Let N be a p-solvable normal subgroup of a finite group G, and Np be a p-Hall subgroup of N . If x is an element of G, then the conjugacy class size |xG| = |G : CG(x)|. Obviously, when CG(x) is a maximal subgroup of G, |xG| is minimal. In this paper, we investigate the structure of Np by assuming that |xG| is 1 or minimal for every p-regular element x of N

在大小为 1 或最小的 p 正则 G 共轭类上

摘要

N是有限群G的p可解正规子群,并且N p '是 N 的p ' -Hall子群。如果xG的一个元素,那么共轭类大小|x G | = |G : CG ( x ) | . 显然,当CG ( x ) 是G的最大子群时,|x G | 是最小的。在本文中,我们研究了N p的结构'通过假设|x G | 对于N的每个p正则元素x为1 或最小值
