On certain tilting modules for $S L_{2}$ II

Samuel Martin

Following the previous work, we determine exactly the highest weights for which a tensor product of two induced modules is a tilting module, for the algebraic group $S L_{2}$ over an…

A Clebsch-Gordan decomposition in positive characteristic

Stephen Donkin, Samuel Martin

Let $G$ be the special linear group of degree $2$ over an algebraically closed field $K$ . Let $E$ be the natural module and $S^{r} E$ the $r$ th symmetric power. We consider here, for…
