关于交换度的几个界

Some bounds on commutativity degree

R. K. Nath, M. K. Yadav

摘要:

有限群$G$的子群$H$的相对交换度,记作$\Pr(H, G)$,是$G$的一个元素与$H$的一个元素交换的概率。本文给出了$\Pr(H, G)$的上、下界及其推论。我们还研究了$\Pr(H, G)$及其推广在群偶等倾下的不变性。

英文摘要:

The relative commutativity degree of a subgroup $H$ of a finite group $G$, denoted by $\Pr(H, G)$, is the probability that an element of $G$ commutes with an element of $H$. In this article we obtain some lower and upper bounds for $\Pr(H, G)$ and their consequences. We also study an invariance property of $\Pr(H, G)$ and its generalizations, under isoclinism of pairs of groups.
