论文摘要
我们将广义的Persutahedra与Schubert演算联系起来。因此,我们为国旗品种的Schubert交叉数字提供了足够的消失标准。我们的论点利用了Schubitopes研究的最新发展,这些研究是舒伯特多项式的牛顿多型。由此产生的Tableau测试在多项式时间内执行。
We connect generalized permutahedra with Schubert calculus. Thereby, we give sufficient vanishing criteria for Schubert intersection numbers of the flag variety. Our argument utilizes recent developments in the study of Schubitopes, which are Newton polytopes of Schubert polynomials. The resulting tableau test executes in polynomial time.
