二元置换群:交错群与典型群

Binary permutation groups: alternating and classical groups

Nick Gill, Pablo Spiga

摘要:

我们引入了一种研究有限二元置换群的新方法,并且作为我们方法的应用,我们证明了Cherlin关于以有限交错群为基柱的群以及有限典型群的$\mathcal{C}_1$ -本原作用的二元群猜想。我们的新方法涉及的概念,定义相对于一个群作用,一个“\emph{beautiful subset}”。我们演示了如何存在这样的子集可以用来表明,一个给定的行动是不是二进制的。特别是,研究这些集将导致决议的许多剩余的开放情况下,切尔林的二元组猜想。

英文摘要:

We introduce a new approach to the study of finite binary permutation groups and, as an application of our method, we prove Cherlin's binary groups conjecture for groups with socle a finite alternating group, and for the $\mathcal{C}_1$-primitive actions of the finite classical groups. Our new approach involves the notion, defined with respect to a group action, of a `\emph{beautiful subset}'. We demonstrate how the presence of such subsets can be used to show that a given action is not binary. In particular, the study of such sets will lead to a resolution of many of the remaining open cases of Cherlin's binary groups conjecture.
