Crystals for Kostant-Kumar modules of $\widehat{\mathfrak{sl}_2}$

Representation Theory 2024-09-17 v1

Abstract

We consider the affine Lie algebra sl2^\widehat{\mathfrak{sl}_2} and the Kostant-Kumar submodules of tensor products of its level 1 highest weight integrable representations. We construct crystals for these submodules in terms of the charged partitions model and describe their decomposition into irreducibles.
