关于子群交换度及相关概念的思考

Considerations on the subgroup commutativity degree and related notions

Francesco G. Russo

摘要:

有限群$G$的子群交换度的概念近年来在群论的几个领域引起了人们的兴趣,因为它给出了随机选取的$G$的子群对$(H,K)$满足条件$HK=KH$的概率的度量。本文研究了一个更强的概念,并找到了它与交换度的关系。

英文摘要:

The concept of subgroup commutativity degree of a finite group $G$ is arising interest in several areas of group theory in the last years, since it gives a measure of the probability that a randomly picked pair $(H,K)$ of subgroups of $G$ satisfies the condition $HK=KH$. In this paper, a stronger notion is studied and relations with the commutativity degree are found.
