Long range divided differences, clusters, and Graham-positivity
Hunter Spink, Vasu Tewari
We study torus-orbit closures in the type complete flag variety naturally associated to cones in the positive cluster fan, together with their left -translates. The torus-…
The Springer Geometry of Specht Polynomials and Schubert cycle positivity for two row Springer fiber components
Hunter Spink, Vasu Tewari
We show that the type A Springer representation is realized geometrically in the homology of the complete flag variety by Specht polynomials. For any partition, we identify the cla…
The Quasisymmetric Grassmannian
Nantel Bergeron, Lucas Gagnon, Hunter Spink +1
We construct a complex of toric varieties we call the quasisymmetric Grassmannian inside the Grassmannian of -planes in . Each irreducible component is a positroid…
The Coxeter Flag Variety
Nantel Bergeron, Lucas Gagnon, Hunter Spink +1
For a Coxeter element in a Weyl group , we define the -Coxeter flag variety as the union of left-translated Richardson varieties $w^{-1}…
