设G为有限群且H≤G,如果存在G的p-幂零子群K,使得G=HK,则称子群H在G中p-幂零可补.将上述条件局部化,即在群G的Sylow子群的正规化子中考察这一性质与有限群构造之间的关系,得到一些有关群G p-幂零与超可解的新结果.
Let G be a finite group.A subgroup H of G is said to be p-nilpotent supplemented in G if there exists a subgroup K of G such that G=HK where K is p-nilpotent.The author localizes the condition,considers the property in the normalizer of Sylow subgroup of G and obtains some new results about nilpotentcy and supersolvability of G.
