研究了U-可补子群对有限群结构的影响.在一些准素子群(例如,Sylow子群的2-极大子群)U-可补的假设下,一些p-幂零性的条件被建立,同时得到了一个群属于给定的有限群的群系的新的刻画.作为应用,推广和统一了一些已知的结果.
The influence of u-supplemented subgroups on the structure of finite groups was investigated.Some conditions of p-nilpotency under assumption that some primary subgroups (for example,2-maximal subgroups of Sylow subgroup) are u-supplemented were established.Meanwhile,some new characterizations of a group belonging to a given formation of finite groups were obtained.As an application,a series of previously known results are unified and generalized.
