摘要:利用子群的幾乎m-嵌入性質(zhì)重新刻畫(huà)了p-冪零群和UΦ-超中心。以幾乎m-嵌入準(zhǔn)素子群為研究對(duì)象,采用局部化處理方法,將幾乎m-嵌入準(zhǔn)素子群分別局部化到Sylow p-子群的正規(guī)化子中和廣義Fitting子群中開(kāi)展研究。得到了一個(gè)刻畫(huà)p-冪零群的充分條件及3個(gè)描述UΦ-超中心結(jié)構(gòu)的3個(gè)充分條件。所得結(jié)論豐富了研究p-冪零群和UΦ-超中心結(jié)構(gòu)的手段。

A note on nearly m-embedded subgroups of finite groups

GAO Baijun1,2, ZHANG Jia1,3, MIAO Long1

Abstract:? p-nilpotent groups and? UΦ-h(huán)ypercentre were investigated by using nearly m-embedded property of subgroups. Nearly m-embedded primary subgroups was took as the research object and localized to the normalizer of Sylow p-subgroups and the generalized Fitting subgroup respectively by adopting localization method. A sufficient condition of p-nilpotent groups and three sufficient conditions on the construction of? UΦ-h(huán)ypercentre were obtained. The researching methods on the structure of? p-nilpotent groups and? UΦ-h(huán)ypercentre were enriched by the obtained results above.

Key words: nearly m-embedded subgroup; p-nilpotency; UΦ-h(huán)ypercentre; primary subgroup

本文討論的都是有限群,涉及的術(shù)語(yǔ)和符號(hào)可見(jiàn)文獻(xiàn)[1-2]。符號(hào)U和N表示超可解群系和冪零群系。

2009年,Shemetkov和Skiba[3]通過(guò)考慮有限群G的非Frattini主因子的G-超中心性質(zhì),定義了有限群G的FΦ-超中心,它不僅包含有限群G的F-超中心,而且是有限群G的F-超中心的自然推廣。2014年,湯菊萍和繆龍[4]利用給定階子群的M-可補(bǔ)性考察了有限群的FΦ-超中心構(gòu)造。2016年,張佳、繆龍和湯菊萍[5]利用子群的M*-可補(bǔ)性對(duì)有限群的UΦ-超中心的結(jié)構(gòu)進(jìn)行了研究。2011年,郭文彬和Skiba[6]引入了Σ-嵌入子群、幾乎m-嵌入的概念,并利用子群的幾乎m-嵌入性質(zhì)對(duì)有限群p-冪零性和相關(guān)群系做了一些研究。其他有關(guān)有限群的p-冪零性及群系的研究還可參考文獻(xiàn)[7-10]。

作為以上研究工作的繼續(xù),我們將利用準(zhǔn)素子群的幾乎m-嵌入性質(zhì)對(duì)有限群的p-冪零性及廣義超中心的結(jié)構(gòu)進(jìn)行研究,并將得到一些新的刻畫(huà)。
