称子群H在群G中M-可补,若存在子群B,使得G=HB,且对于H的任意极大子群H1,都有H1B为G的真子群。将子群的性质局部化,在群G的Sylow子群的正规化子中来考察子群的M-可补性,对有限群构造作进一步探索得到p-幂零、超可解的一些新结果。
Properties of the subgroups have been localized in order to consider the M-supplementation of NG(P),where P is the Sylow p-subgroup of G,and some results about p-nilpotency and super-solvability have been obtained.
