设G是有限群,A和B都是其子群.若G=AB,则称G为乘积因子群.研究乘积因子群中某些元素的共轭类长对有限群的可解性、超可解性和p-幂零性的影响,所得结果推广了若干相关的新近结果.
Let G be a finite group, and A, B be its subgroups. If G = AB, then G was called a factorized group. The influences of lengths of eonjugacy classes of some elements in factorized groups on the solvability, supersolvability and p-nilpotency of finite groups were studied. Some recent related results were generalized.
