摘要
设F是一个群类,H≤G.如果存在K≤G使HK=G且K/HG∩K∈F,那么称H在G中是F-s-可补的.K称为H在G中的F-s-补.本文我们用子群的F-s-补研究了群的结构,得到了一些有意义的结果.
Let £of groups and H≤G. If K≤G such that HK=G and K/Hg∩k∈£,then H is called £-s-supplemented in G.And we call K a £-s-supplement of H in G.Here,we study the structure of finite groups with £-s-supplement of some subgroups and get some useful results.
