s-半置换子群对群的幂零性的影响
Influences of s-semipermutablility of Subgroups on p-nilpotence of Finite Groups
【摘要】 群G的子群H称为半置换的,若对任意的K≤G,只要(|H|,|K|)=1,就有HK=KH,H称为s-半置换的,若对任意的p‖G|,只要(p,|H|)=1,就有PH=HP,其中P∈Sylp(G).本文利用极小子群的s-半置换性得到幂零群的若干充分条件.
【Abstract】 A subgroup H of a group G is called semipermutable if it is permutable with every subgroup K of G with(|H|,|K|)=1,and s-semipermutable if it is permutable with every Sylow p-subgroup of G with((p,|H|))=1.With s-semipermutability of the minimal subgroups,some sufficient conditions of p-nilpotent and nilpotent group are obtained in this paper.
