On Weyl modules over affine Lie algebras in prime characteristic

Representation Theory 2016-11-15 v5 Quantum Algebra

Abstract

We construct a family of homomorphisms between Weyl modules for affine Lie algebras in characteristic p, which supports our conjecture on the strong linkage principle in this context. We also exhibit a large class of reducible Weyl modules beyond level one, for p not necessarily small.
