A tableau formula of double Grothendieck polynomials for $321$-avoiding permutations (1711.00147v1)
Published 1 Nov 2017 in math.CO and math.AG
Abstract: In this article, we prove a tableau formula for the double Grothendieck polynomials associated to $321$-avoiding permutations. The proof is based on the compatibility of the formula with the $K$-theoretic divided difference operators.
