The "Grothendieck to Lascoux" conjecture
arXiv (Cornell University)(2021)
摘要
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.
