我们证明了一个新的配方的K理论Pieri规则的乘法稳定Grothendieck多项式使用迭代剩余。我们还部署我们的方法来建立矫直法律,将Grothendieck多项式对应的一般整数序列的线性组合对应的分区。迭代留数的技巧看起来立刻类似于提升算子;然而,与复平面中的路径积分的联系提供了不同的视角。
We prove a new formulation of the K-theoretic Pieri rule regarding multiplication of stable Grothendieck polynomials using iterated residues. We also deploy our method to establish straightening laws to transform Grothendieck polynomials corresponding to general integer sequences to linear combinations of those corresponding to partitions. The technique of iterated residues appears at once similar to raising operators; however, the connection to path integrals in the complex plane provides a different perspective.
