具有两个相对子群交换度的有限群

Finite groups with two relative subgroup commutativity degrees

Mihai-Silviu Lazorec, Marius Tărnăuceanu

摘要:

本文证明了存在无穷多个具有两个相对子群交换度的有限群。给出了有限群至少有三个相对子群交换度的充分条件,证明了$D_6$是唯一具有两个相对交换度的有限二面体群.最后,我们研究了包含有限群的所有子群交换度的集合的稠密性。

英文摘要:

In this paper we show that there is an infinite number of finite groups with two relative subgroup commutativity degrees. Also, we indicate a sufficient condition such that a finite group has at least three relative subgroup commutativity degrees and we prove that $D_6$ is the only finite dihedral group with two relative commutativity degrees. Finally, we study the density of the set containing all subgroup commutativity degrees of finite groups.
