G_2的可约子群

The Reductive Subgroups of G_2

David I. Stewart

摘要:

设$G:=G_2(K)$是定义在特征为$p>0$的代数闭域$K$上的$G_2$型单代数群.令$σ$表示$G$的标准Frobenius自同构,使得$G_σ\cong G_2(q)$与$q\geq 4$。本文在定义特征中找到了$G$的所有约化子群和$G_σ$的拟单群。

英文摘要:

Let $G:=G_2(K)$ be a simple algebraic group of type $G_2$ defined over an algebraically closed field $K$ of characteristic $p>0$. Let $σ$ denote a standard Frobenius automorphism of $G$ such that $G_σ\cong G_2(q)$ with $q\geq 4$. In this paper we find all reductive subgroups of $G$ and quasi-simple subgroups of $G_σ$ in the defining characteristic.
