子群H称为在G中弱拟正规的,如果对任意K G,至少存在一个K的共轭子群Kx,x∈G,使得HKx=KxH.利用子群的弱拟正规性刻画群的结构.
A subgroup H of a group G is said to be weakly quasinormal subgroups in G if there exists an element x ∈ G such that HK^x = K^xH . In this paper we determine the structure of finite groups by weakly quasinormal condition of subgroups.
