In this paper we discuss the influence on an original finite group G when its Sylow subgroups and other subgroups are weakly quasi-normal,then we obtain some sufficient conditions for supersoluability of group G.
主要讨论了群G的Sylow子群及其他子群的弱拟正规性对群的影响,从而得到原群G超可解的几个充分条件的定理:1)群G有指数为素数的可解正规子群H,若H的每个Sylow子群的极大子群在G中弱拟正规,则G超可解;2)群G有指数为素数的正规子群H,若H的Sylow子群及Sylow子群的2-极大子群皆在G内弱拟正规,则G超可解;3)设G=AB,A超可解,B是P-群,p=maxπ(G),若B与A的极大子群可交换且A弱拟正规于G,则G超可解;4)M为G的幂零极大子群,若M及其极大子群皆在G中弱拟正规,则G超可解。
