关于有限群的不可约特征[标]的限制和零元的注记
We establish a relation between the ratio of the order of a non-abelian finite group G to the number of irreducible character of the group and the stucture of the group G,and obtain the lower bound of the ratio by the mininal prime divisor of the order and commutator of the group G,and give a necessary and sufficient condition which attains this lower bound.
本文研究了一般的非交换有限群G的阶与不可约特征[标]个数的比值与群G结构之间的关系。
In this note,we study a finite π-separable group G with every nonlinear irreducible characters being of π-degree,and get a equivalent condition for G being a π-group,some group theoretic characterizations are also given.
这篇文章中 ,我们研究了一种有限π -可分群G ,它的每一个非线性不可约特征[标]是π -次的 ,得到了G是π -群的一个等价条件 ,并且给出了一些群理论的特征。
In this paper groups,we prove that groups with two irreducible character degrees are supersolvable.
证明了具有两个不可约特征[标]级数的群是超可解群,并说明了二面体群,四次交错群,三次对称群是超可解群。
In this paper,it is proved by using the character that inducing irreducible nonprincipal characters of some subgroup of a finite group is still irreducible .

In chapter 2, we have proved a theorem in terms of faithful irreducible characters; in chapter 3, we have explored groups of central type and properties of its characters.
忠实不可约特征[标]在特征标乘积的研究中起着很重要的作用。
In fact, how the number and the degree of nonlinear irreducible characters of finite groups influnce the structure of groups is an important issue of category theory.
事实上,有限群的非线性不可约特征[标]个数和次数如何影响群的结构已成为有限群常表示论的一个重要研究课题。
