极小子群与有限群的结构研究
Minimal subgroups and the study of the structure of finite groups
【摘要】 首先利用极小子群的中心化子和正规化子对若干有限群的结构进行了刻画,其次给出了非平凡交换子群个数≤4的有限群的完全分类.
【Abstract】 In this paper,we firstly characterize the structure of some finite groups through the centralizers and normalizers of minimal subgroups,secondly we obtain the complete classification of finite groups whose the quantity of nontrivial abelian subgroups is not more than four.
