设G是有限群,H是群G的一个子群.如果存在G的正规子群K,使得HK△G且对于H的任意极大子群T,有TK〈HK,则称子群H为在G中是几乎M可补的.本文主要利用某些准素子群的几乎M可补性质来研究有限群的结构,得到了群G为P超可解和超可解的相关结果.
Let G be a finite group. A subgroup H of G is said to be nearly M-supplemented inG if there exists a nor- mal subgroup K of G such that HK △1 G and TK〈HK for every maximal subgroup T of H. In this paper,we will obtain some results about p-supersolvability and supersolvability of G by using the property of the nearly M-supple- mented subgroup of G.
