代数群中类的积与积子

Products and commutators of classes in algebraic groups

Robert Guralnick, Gunter Malle

摘要:

本文对几乎单代数群中的共轭类对进行分类,其乘积由多个类组成。这导致了几个有趣的家庭的例子,这是有关的推广贝尔-铃木定理的有限群。我们还回答了一个问题的帕维尔舒米亚茨基对单代数群的共轭类的分解。事实证明,所得到的例子正是那些产品也只包含1000个类的例子。

英文摘要:

We classify pairs of conjugacy classes in almost simple algebraic groups whose product consists of finitely many classes. This leads to several interesting families of examples which are related to a generalization of the Baer--Suzuki theorem for finite groups. We also answer a question of Pavel Shumyatsky on commutators of pairs of conjugacy classes in simple algebraic groups. It turns out that the resulting examples are exactly those for which the product also consists of only finitely many classes.
