摘要
称群G为π-闭-Sylow塔群,若群G存在正规Hallπ-子群为Sylow塔群.本文在π-闭-Sy-low塔群的性质的基础上,利用s-拟正规的性质,给出了一个群为π-闭-Sylow塔群的一些条件.
A group G is called a π-closed-Sylow-tower group if there exists a normal Hall π-subgroup in G, which is a Sylow-tower group. Discussion is made on the sufficient conditions for π-closed-Sylow-tower groups through the use of the properties of s-quasinormal subgroups.
