This paper studies extension groups between certain Weyl modules for the algebraic group
GLn over the integers. Main results include:(1) a complete determination of Ext groups …

This paper concerns representations of the integral general linear group. The extension
groups Ext 2 between any pair of hook Weyl modules are determined via a detailed study of …

Let 2n (K) be the Kostant form of i (sl+ n) and Γ the monoid generated by the positive roots of
sln. For each λ∈ Λ (n, r) we construct a functor Fλ from the category of finitely generated Γ …

Let G= GLn (k), the group of all invertible nxn matrices over an infinite field k. In this thesis
we explore the cohomological relationship between a Schur algebra S (G) for G and the …

Let $ A_n (K) $ be the Kostant form of $\mathfrak {U}(sl_n^+) $ and $\Gamma $ the monoid
generated by the positive roots of $ sl_n $. For each $\lambda\in\Lambda (n, r) $ we …
