On homomorphisms involving a hook Weyl module

Mihalis Maliakas, Dimitra-Dionysia Stergiopoulou

Let $k$ be an infinite field of positive characteristic. We determine all homomorphisms between Weyl modules for $G L n (k)$ , where one of the partitions is a hook. As a consequence w…

On extensions of hook Weyl modules

Mihalis Maliakas, Dimitra-Dionysia Stergiopoulou

We determine the integral extension groups $E x t^{1} (Δ (h), Δ (h (k)))$ and $E x t^{k} (Δ (h), Δ (h (k)))$ , where $Δ (h), Δ (h (k))$ are the Weyl modules of the general linear group $G L_{n}$ correspondi…
