我们计算牛顿Okounkov机构的线丛的GLn的完整的ag品种的几何估值来自一个ag的翻译舒伯特子品种。舒伯特子簇对应于Weyl群中最长元素的分解(s1)(s2 s1)(s3 s2 s1)(sn)(sn-1 <$s1)中的终止子字。由此得到的Newton-Okounkov体与A型的Feigin-Fourier-Littelmann-Vinberg多面体一致。
We compute the Newton–Okounkov bodies of line bundles on the complete ag variety of GLn for a geometric valuation coming from a ag of translated Schubert subvarieties. The Schubert subvarieties correspond to the terminal subwords in the decomposition (s1)(s2s1)(s3s2s1)(⋯)(sn–1⋯s1) of the longest element in the Weyl group. The resulting Newton–Okounkov bodies coincide with the Feigin–Fourier–Littelmann–Vinberg polytopes in type A.
