The Nil Hecke Ring and Singularity of Schubert Varieties
Let G be a semi-simple simply-connected complex algebraic group and T ⊂ B a maximal torus and a Borel subgroup respectively. Let h = Lie T be the Cartan subalgebra of the Lie algebra Lie G, and W := N(T )/T the Weyl group associated to the pair (G, T ), where N(T ) is the normalizer of T in G. We can view any element w = w mod T ∈ W as the element (denoted by the corresponding German character)...
متن کاملThe nil Hecke ring and cohomology of G/P for a Kac-Moody group G.
Let G be the group with Borel subgroup B, associated to a Kac-Moody Lie algebra [unk] (with Weyl group W and Cartan subalgebra [unk]). Then H(*)(G/B) has, among others, four distinguished structures (i) an algebra structure, (ii) a distinguished basis, given by the Schubert cells, (iii) a module for W, and (iv) a module for Hecke-type operators A(w), for w [unk] W. We construct a ring R, which ...
متن کاملAffine Hecke algebras and the Schubert calculus
Using a combinatorial approach which avoids geometry, this paper studies the ring structure of KT (G/B), the T -equivariant K-theory of the (generalized) flag variety G/B. Here, the data G ⊇ B ⊇ T is a complex reductive algebraic group (or symmetrizable Kac-Moody group)G, a Borel subgroup B, and a maximal torus T , and KT (G/B) is the Grothendieck group of T -equivariant coherent sheaves on G/B...
متن کاملMultiplicities on Schubert Varieties
We calculate using Macaulay 2 the multiplicities of the most singular point on Schubert varieties on Gl(n)/B for n = 5, 6. The method of computation is described and tables of the results are included.
متن کاملLarge Schubert Varieties
For a semisimple adjoint algebraic group G and a Borel subgroup B, consider the double classes BwB in G and their closures in the canonical compactification of G; we call these closures large Schubert varieties. We show that these varieties are normal and Cohen-Macaulay; we describe their Picard group and the spaces of sections of their line bundles. As an application, we construct geometricall...
