On the Topology of the Combinatorial Flag Varieties
For any positive integer n, let [n] denote the set {1, . . . , n}, and letMn be the set of all matroids on [n]. Throughout this paper all matroids will have ground set [n], and we shall frequently omit the symbol n from our notation. Define a partial ordering on Mn by M ′ ≤ M if M ′ is a quotient of M . Let Ωn be the simplicial complex of chains in Mn ; every simplex s ∈ Ωn can be written as s ...
متن کاملParametrizations of Flag Varieties
For the flag variety G/B of a reductive algebraic group G we define and describe explicitly a certain (set-theoretical) cross-section φ : G/B → G. The definition of φ depends only on a choice of reduced expression for the longest element w0 in the Weyl group W . It assigns to any gB a representative g ∈ G together with a factorization into simple root subgroups and simple reflections. The cross...
متن کاملCombinatorics in affine flag varieties
The Littelmann path model gives a realisation of the crystals of integrable representations of symmetrizable Kac-Moody Lie algebras. Recent work of Gaussent-Littelmann [GL] and others [BG] [GR] has demonstrated a connection between this model and the geometry of the loop Grassmanian. The alcove walk model is a version of the path model which is intimately connected to the combinatorics of the a...
متن کاملShelling Totally Nonnegative Flag Varieties
In this paper we study the partially ordered set Q of cells in Rietsch’s [20] cell decomposition of the totally nonnegative part of an arbitrary flag variety P ≥0 . Our goal is to understand the geometry of P ≥0 : Lusztig [13] has proved that this space is contractible, but it is unknown whether the closure of each cell is contractible, and whether P ≥0 is homeomorphic to a ball. The order comp...
متن کاملEquivariant Sheaves on Flag Varieties
We show that the Borel-equivariant derived category of sheaves on the flag variety of a complex reductive group is equivalent to the perfect derived category of dg modules over the extension algebra of the direct sum of the simple equivariant perverse sheaves. This proves a conjecture of Soergel and Lunts in the case of flag varieties.
