有限群G 的子群H 称为在G 中c- 可补,如果存在G 的子群K 使得HK =G 且H ∩K ≤CoreG (H ).该文利用极小子群的局部c- 可补性,得到有限群成为p-幂零群的两个充要条件.作为应用,一些熟知的结果得到推广.
A subgroup H is said to be c supplcmnted in a finite group G if there exists a subgroup K of G such that HK= G and H K is contained in (oreG (H). In this paper, we obtain two st, fficient and necessary conditions of p nilpotence of finite groups by using locally c supplcmcnted minimal subgroups. As application, some known re sults were generalized.
