有限群G的子群H叫做在G中弱SS-可补,如果存在G的子群K使得HK是G的次正规子群且H∪K≤HwG其中HwG是G的含于H的最大次正规子群.该文利用Sylow子群的某些弱SS-可补子群来刻画有限群的可解性.
A subgroup H of a group G is said to be weakly ss-supplemented in G if there exists a subgroup K of G such that HK is a subnormal subgroup of G and H∩ K≤H,G, where HuG is the largest subnormal subgroup of G contained in H. In this paper, the solvability of a finite group G with rome subgroups of Sylow subgroups weakly ss-supple- mented in Gis characterized.
