设是一个有限群,为的子群,如果对于的任意Sylow子群的极大子群,至少存在的一个共轭子群,,使得,则称子群为的PCSM-子群.本文利用群的PC-SM-子群获得了群为超可解群的一个充要条件.
Suppose G is a limited group and H is a subgroup of G,subgroup H of G is called PCSM-Subgroups in G if there exists at least one G-conjugate of each maximal subgroup M of any Sylow subgroup of G,such that HMx=MxH for some xG.In this paper,a sufficient or necessary condition of a finite group G which is P-supersolvable is obtained by using the PCSM-Subgroups of G.
