交换子群的正规化子和中心化子对有限群的结构有很强的控制作用,本文通过对少量交换子群的正规化子和中心化子做适当限制,得到有限群为p-幂零群、幂零群、超可解群的若干充分条件,推广了著名的Frebenius定理.
The normalizers and centralizers of Abelian sugroups give a lot of information about the struc-ture of finite groups. In this paper, some interesting results related to the Abelian subgroups are ob-tained.
