The second cohomology of simple SL_3-modules

David I. Stewart

Let G be the simple, simply connected algebraic group SL_3 defined over an algebraically closed field K of characteristic p>0. In this paper, we find H^2(G,V) for any irreducible G…

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…
