Towards a Combinatorial Model for -weight Multiplicities of Simple Lie Algebras (Extended Abstract)
Cédric Lecouvey, Cristian Lenart, Adam Schultze
Kostka-Foulkes polynomials are Lusztig's -analogues of weight multiplicities for irreducible representations of semisimple Lie algebras. It has long been known that these polyno…

On Combinatorial Models for Affine Crystals
Carly Briggs, Cristian Lenart, Adam Schultze
The tableau model for Kirillov-Reshetikhin (KR) crystals, which are finite dimensional crystals corresponding to certain affine Lie algebras, is commonly used for its ease of cryst…
