摘要:

有限群 G 的一个子群 H 称为在 G 中 π - 拟正规的, 如果 HG的每一个Sylow子群可交换. 自从这一概念被 Kegel 提出后, 许多学者相继研究了某些子群在G中的 π - 拟正规性对有限群结构的影响.该文将上述条件局部化,即在群 G 的Sylow 子群的正规化子中来研究这一性质与有限群结构之间的关系.

关键词: 有限群, 极大子群, &pi, - 拟正规, 饱和群系

Abstract:

A subgroup of a group G is said to be π-quasinormal in G if it permutes with every Sylow subgroup of G, which was firstly posed by Kegel. Since then,
a long series of papers deal with π-quasinormality well located in G. In this paper we localize the above conditions in the G-normalizer of Sylow subgroups of the group G.

Key words: Finite groups, Maximal subgroups, π-quasinormal, Saturated formations
