本文引入了具有两个无限参数序列的精化规范稳定Grothendieck多项式及其对偶。这些多项式统一了Grothendieck多项式的几种推广,包括由于Yeliussizov的规范稳定Grothendieck多项式,由于Chan和Pflueger的精细Grothendieck多项式,以及由于Galashin,Liu和Grinberg的精细双Grothendieck多项式。我们给出Jacobi-Trudi公式,组合模型,Schur展开,Schur正性,以及这些多项式的对偶。
In this paper we introduce refined canonical stable Grothendieck polynomials and their duals with two infinite sequences of parameters. These polynomials unify several generalizations of Grothendieck polynomials including canonical stable Grothendieck polynomials due to Yeliussizov, refined Grothendieck polynomials due to Chan and Pflueger, and refined dual Grothendieck polynomials due to Galashin, Liu, and Grinberg. We give Jacobi–Trudi-like formulas, combinatorial models, Schur expansions, Schur positivity, and dualities of these polynomials.
