G-complete reducibility and the exceptional algebraic groups

David I. Stewart

Let $G = G (K)$ be a simple algebraic group defined over an algebraically closed field $K$ of characteristic $p > 0$ . A subgroup $X$ of $G$ is said to be $G$ -completely reducible if, wh…

The second cohomology of simple SL_2-modules

David I. Stewart

Let $G$ be the simple algebraic group $S L_{2}$ defined over an algebraically closed field $K$ of characteristic $p > 0$ . In this paper, we find the second cohomology of all irreducible…

The Reductive Subgroups of G_2

David I. Stewart

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 o…
