关于有限π－幂零群的几个充分条件

SUFFICIENT CONDITIONS FOR A FINITE GROUP AS NILPOTENT

在文献［１］研究π－可解群的π－性质的基础上，利用其定义的π－中心和π－超中心的概念，得到了有限π－可解群为π－幂零群的几个充分条件，并给出了π－超中心的两个刻划。

There have been many results in the field ofπ-nilpotent group retsearch. basedon a reference,in which π-soluble group of π-properties is studied, by the use ofπ-center andπ-hypercenter.another sufficient conditionS for π-niloptent group can be obtained.Twoportrayals of π-hypercenter are given。
