群中的 z-类:综述

z-classes in groups: a survey

Sushil Bhunia, Anupam Singh

AI总结:

本文综述了群中 z-类的概念,梳理其与轨道型及 Lie 型有限群表示论中型或亏格的联系,总结已知结果并提出进一步问题。

摘要:

这篇综述文章探讨了群中 z-类的概念。这里引入的概念与变换群中的轨道型概念,以及 Lie 型有限群表示论中的型或亏格概念相关。群中两个元素被称为 z-等价(或 z-共轭),如果它们的中心化子是共轭的。这是比元素共轭更弱的概念。在这篇综述文章中,我们介绍了关于这一主题的若干已知结果,并提出了一些进一步的问题。

英文摘要:

This survey article explores the notion of z-classes in groups. The concept introduced here is related to the notion of orbit types in transformation groups, and types or genus in the representation theory of finite groups of Lie type. Two elements in a group are said to be z-equivalent (or z-conjugate) if their centralizers are conjugate. This is a weaker notion than the conjugacy of elements. In this survey article, we present several known results on this topic and suggest some further questions.
