Notes on Schubert, Grothendieck and Key Polynomials (1501.07337v3)
Published 29 Jan 2015 in math.CO
Abstract: We introduce common generalization of (double) Schubert, Grothendieck, Demazure, dual and stable Grothendieck polynomials, and Di Francesco-Zinn-Justin polynomials. Our approach is based on the study of algebraic and combinatorial properties of the reduced rectangular plactic algebra and associated Cauchy kernels.
