Determinantal formulas for dual Grothendieck polynomials

Published 9 Mar 2020 in math.CO | (2003.03907v2)

Abstract: We prove Jacobi-Trudi-type determinantal formulas for skew dual Grothendieck polynomials which are $K$-theoretic deformations of Schur polynomials. We also prove a bialternant-type formula analogous to the classical definition of Schur polynomials.
