多项式的三种基的组合规则

Combinatorial rules for three bases of polynomials

Colleen Ross, Alexander Yong

摘要:

本文给出了关于Z[x1,x2,…]的三个基的组合规则(一个定理和两个定理).首先,我们证明了一个“分裂”规则的基础上的关键多项式[Demazure '74],从而建立了一个新的正性定理。其次,我们引入了一个扩展[Kohnert '90]的“移动”猜想的第一个组合规则的一定变形[Lascoux '01]的关键多项式。第三,我们使用相同的扩展猜想一个新的规则的Grothendieck多项式[Lascoux-Schutzenberger '82]。

英文摘要:

We present combinatorial rules (one theorem and two conjectures) concerning three bases of Z[x1,x2,....]. First, we prove a "splitting" rule for the basis of key polynomials [Demazure '74], thereby establishing a new positivity theorem about them. Second, we introduce an extension of [Kohnert '90]'s "moves" to conjecture the first combinatorial rule for a certain deformation [Lascoux '01] of the key polynomials. Third, we use the same extension to conjecture a new rule for the Grothendieck polynomials [Lascoux-Schutzenberger '82].
