A Combinatorial Model for Crystals of Kac-Moody Algebras
Cristian Lenart, Alexander Postnikov
We present a simple combinatorial model for the characters of the irreducible integrable highest weight modules for complex symmetrizable Kac-Moody algebras. This model can be view…

On Characters of Weyl Groups
Ron M. Adin, Alexander Postnikov, Yuval Roichman
In this note a combinatorial formula related to the symmetric group is generalized to an arbitrary finite Weyl group.

Hecke Algebra Actions on the Coinvariant Algebra
Ron M. Adin, Alexander Postnikov, Yuval Roichman
Two actions of the Hecke algebra of type A on the corresponding polynomial ring are studied. Both are deformations of the natural action of the symmetric group on polynomials, and…
