Coxeter combinatorics for sum formulas in the representation theory of algebraic groups

Jonathan Gruber

Let $G$ be a simple algebraic group over an algebraically closed field $F$ of characteristic $p \geq h$ , the Coxeter number of $G$ . We observe an easy `recursion formula' f…

On complete reducibility of tensor products of simple modules over simple algebraic groups

Jonathan Gruber

Let $G$ be a simply connected simple algebraic group over an algebraically closed field $k$ of characteristic $p > 0$ . The category of rational $G$ -modules is not semisimple. We cons…
