We study the toric degeneration of Weyl group translated Schubert divisors of a partial flag variety F`n1,n2,··· ,nk;n via Gelfand-Cetlin polytopes. We propose a conjecture that Schubert varieties of appropriate dimensions intersect transversally up to translation by Weyl group elements, and verify it in various cases, including complex Grassmannian Gr(2, n) and complete flag variety F`1,2,3;4.

Degenerations of Flag and Schubert Varieties to Toric Varieties
In this paper, we prove the degenerations of Schubert varieties in a minuscule G=P , as well as the class of Kempf varieties in the ag variety SL(n)=B, to (normal) toric varieties. As a consequence,Expand
Toric degeneration of Schubert varieties and Gelfand¿Tsetlin polytopes

Schubert calculus and Gelfand-Zetlin polytopes
A new approach is described to the Schubert calculus on complete flag varieties, using the volume polynomial associated with Gelfand-Zetlin polytopes. This approach makes it possible to compute theExpand
General isotropic flags are general (for Grassmannian Schubert calculus)
We show that general isotropic flags for odd-orthogonal and symplectic groups are general for Schubert calculus on the classical Grassmannian in that Schubert varieties defined by such flags meetExpand
Gröbner geometry of Schubert polynomials
Given a permutation w ?? Sn, we consider a determinantal ideal Iw whose generators are certain minors in the generic n ?~ n matrix (filled with independent variables). Using ?emultidegrees?f asExpand
A Littlewood–Richardson rule for two-step flag varieties
This paper studies the geometry of one-parameter specializations of subvarieties of Grassmannians and two-step flag varieties. As a consequence, we obtain a positive, geometric rule for expressingExpand
TORIC VARIETIES
We study toric varieties over a field k that split in a Galois extension K/k using Galois cohomology with coefficients in the toric automorphism group. This Galois cohomology fits into an exactExpand
Pseudotoric structures and special Lagrangian torus fibrations on certain flag varieties
Abstract We construct pseudotoric structures (a la Tyurin, 2010) on the two-step flag variety F l 1 , n − 1 ; n , and explain a general relation between pseudotoric structures and special LagrangianExpand
Mutations of puzzles and equivariant cohomology of two-step flag varieties
We introduce a mutation algorithm for puzzles that is a three-direction analogue of the classical jeu de taquin algorithm for semistandard tableaux. We apply this algorithm to prove our conjecturedExpand
