有限群π-中心与π-special特征标的关系

The Relation Between Finite Group π-center and π-special Characters

在这篇文章中,定义了有限群的π-中心,利用π-中心和π-special特征标的概念,将有限群的中心与不可约特征标的一些结果推广到π-中心和π-special特征标上,我们的结论推广了某些经典结果。

The definition of： π-center of a finite group is given, and some results of finite group center and irreducible characters are generalized to the case of π-center and π-special characters by using the definition of π-center and π-special characters. Some classical theories are special cases of our theries.
