Categorification of a recursive formula for Kazhdan-Lusztig polynomials
arXiv:1503.02742
Abstract
We obtain explicit branching rules for graded cell modules and graded simple modules over the endomorphism algebra of a Bott-Samelson bimodule. These rules allow us to categorify a well-known recursive formula for Kazhdan-Lusztig polynomials.
