FINITE p-groupS WHICH CONTAIN A SELF-CENTRALIZING CYCLIC NORMAL SUBgroup
收藏 引用
Acta Mathematica Scientia 2013年 第1期33卷 131-138页
作者: 郝成功 靳竹萱 School of Mathematical Sciences Shanxi University School of Mathematical Sciences Peking University
For any prime p, all finite noncyclic p-groups which contain a self-centralizing cyclic normal subgroup are determined by using cohomological techniques. Some applications are given, including a character theoretic de... 详细信息

R. China Institute of Mathematics Fudan University Shanghai P. R. China
In this paper we consider the isomorphic classes of H-Galois extensions with the normal basis property over a fixed commutative ring B for a finite Hopf algebra *** result is that when H is cocommutative,then the abov... 详细信息
