On the partial Ξ  \Pi -property of some subgroups of prime power order of finite groups

Abstract

Let H H be a subgroup of a finite group G G . We say that H H satisfies the partial Ξ  \Pi -property in G G if if there exists a chief series Ξ“G:1=G0<G1<β‹…β‹…β‹…<Gn=G \varGamma_{G}: 1 =G_{0} < G_{1} < \cdot\cdot\cdot < G_{n}= G of G G such that for every G G -chief factor Gi/Giβˆ’1(1≀i≀n) G_{i}/G_{i-1} (1\leq i\leq n) of Ξ“G \varGamma_{G} , ∣G/Giβˆ’1:NG/Giβˆ’1(HGiβˆ’1/Giβˆ’1∩Gi/Giβˆ’1)∣ | G / G_{i-1} : N_{G/G_{i-1}} (HG_{i-1}/G_{i-1}\cap G_{i}/G_{i-1})| is a Ο€(HGiβˆ’1/Giβˆ’1∩Gi/Giβˆ’1) \pi (HG_{i-1}/G_{i-1}\cap G_{i}/G_{i-1}) -number. In this paper, we study the influence of some subgroups of prime power order satisfying the partial Ξ  \Pi -property on the structure of a finite group.Comment: arXiv admin note: substantial text overlap with arXiv:2304.11451. text overlap with arXiv:1301.6361 by other author
