LLT polynomial
From Wikipedia, the free encyclopedia
Template:Short description In mathematics, an LLT polynomial is one of a family of symmetric functions introduced as q-analogues of products of Schur functions.[1]
J. Haglund, M. Haiman, and N. Loehr showed how to expand Macdonald polynomials in terms of LLT polynomials.[2] Ian Grojnowski and Mark Haiman proved a positivity conjecture for LLT polynomials that combined with the previous result implies the Macdonald positivity conjecture for Macdonald polynomials, and extended the definition of LLT polynomials to arbitrary finite root systems.[3]
