Equivariant Schubert Calculus

چکیده
Let T be a torus acting on C in such a way that, for all 1 ≤ k ≤ n, the induced action on the grassmannian G(k, n) has only isolated fixed points. The T -equivariant cohomology of G(k, n) can be realized, in this case, as the quotient of a ring generated by derivations on the exterior algebra of a free module of rank n over the T -equivariant cohomology of a point. This result allows a simple explicit description of T -equivariant Schubert calculus on grassmannians.

متن کاملEquivariant Quantum Schubert Polynomials
We establish an equivariant quantum Giambelli formula for partial flag varieties. The answer is given in terms of a specialization of universal double Schubert polynomials. Along the way, we give new proofs of the presentation of the equivariant quantum cohomology ring, as well as Graham-positivity of the structure constants in equivariant quantum Schubert calculus.
متن کاملCristian Lenart, Schubert Calculus Beyond K-Theory
Modern Schubert calculus has been mostly concerned with the study of the cohomology andK-theory (including their equivariant and quantum generalizations) of flag manifolds. The basic results for other cohomology theories have only been obtained recently; additional complexity is due to the dependence of the geometrically defined classes on reduced words for the corresponding Weyl group elements...
متن کاملExcited Young Diagrams and Equivariant Schubert Calculus
We describe the torus-equivariant cohomology ring of isotropic Grassmannians by using a localization map to the torus fixed points. We present two types of formulas for equivariant Schubert classes of these homogeneous spaces. The first formula involves combinatorial objects which we call “excited Young diagrams” and the second one is written in terms of factorial Schur Qor P -functions. As an ...
