Multiplicative rule in the Grothendieck cohomology of a flag variety
نویسنده
چکیده
In the Grothendieck cohomology of a flag variety G/H there are two canonical additive bases, namely, the Demazure basis [D] and the Grothendieck basis [KK]. We present explicit formulae that reduce the multiplication of these basis elements to the Cartan numbers of G.

Combinatorial Aspects of the Cohomology and K-theory of Flag Varieties
In this talk we present some recent results related to Schubert and Grothendieck polynomials. These polynomials represent Schubert classes, which form the natural bases of the cohomology and K-theory of the complex flag variety. We present background information on several combinatorial constructions of Schubert and Grothendieck polynomials. Then we present the solution to a conjecture concerni...
متن کاملQuantum Grothendieck Polynomials
Quantum K-theory is a K-theoretic version of quantum cohomology, which was recently defined by Y.-P. Lee. Based on a presentation for the quantum K-theory of the classical flag variety Fln, we define and study quantum Grothendieck polynomials. We conjecture that they represent Schubert classes (i.e., the natural basis elements) in the quantum K-theory of Fln, and present strong evidence for thi...
متن کاملA Pieri-type Formula for the Equivariant Cohomology of the Flag Manifold
The classical Pieri formula is an explicit rule for determining the coefficients in the expansion s1m · sλ = ∑ c 1,λ sμ , where sν is the Schur polynomial indexed by the partition ν. Since the Schur polynomials represent Schubert classes in the cohomology of the complex Grassmannian, this gives a partial description of the cup product in this cohomology. Pieri’s formula was generalized to the c...
متن کاملAlgorithm for Multiplying Schubert Classes
Based on the multiplicative rule of Schubert classes obtained in [Du3], we present an algorithm computing the product of two arbitrary Schubert classes in a flag variety G/H, where G is a compact connected Lie group and H ⊂ G is the centralizer of a one-parameter subgroup in G. Since all Schubert classes on G/H constitute an basis for the integral cohomology H∗(G/H), the algorithm gives a metho...
متن کاملExtended quadratic algebra and a model of the equivariant cohomology ring of flag varieties
For the root system of type A we introduce and study a certain extension of the quadratic algebra invented by S. Fomin and the first author, to construct a model for the equivariant cohomology ring of the corresponding flag variety. As an application of our construction we describe a generalization of the equivariant Pieri rule for double Schubert polynomials. For a general finite Coxeter syste...
