The "Grothendieck to Lascoux" conjecture (2102.12399v1)
Published 24 Feb 2021 in math.CO
Abstract: This report formulates a conjectural combinatorial rule that positively expands Grothendieck polynomials into Lascoux polynomials. It generalizes one such formula expanding Schubert polynomials into key polynomials, and refines another one expanding stable Grothendieck polynomials.
