有限群共轭类大小的重数

Multiplicities of conjugacy class sizes of finite groups

Hung Ngoc Nguyen

摘要:

Moreto和Craven最近证明了一个有限群的阶是用它的不可约特征标的最大重数有界的。Zaikin-Zapirain对可解群证明了这个结果的一个共轭类形式。本文证明了:若$G$是有限单群,则用$|G|$表示的$G$的阶是以其共轭类大小的最大重数有界的;若有限群$G$的任意商的共轭类大小的最大重数是$m$,则$|G|$是以$m$有界的.

英文摘要:

It has been proved recently by Moreto and Craven that the order of a finite group is bounded in terms of the largest multiplicity of its irreducible character degrees. A conjugacy class version of this result was proved for solvable groups by Zaikin-Zapirain. In this note, we prove that if $G$ is a finite simple group then the order of $G$, denoted by $|G|$, is bounded in terms of the largest multiplicity of its conjugacy class sizes and that if the largest multiplicity of conjugacy class sizes of any quotient of a finite group $G$ is $m$, then $|G|$ is bounded in terms of $m$.
