متن کاملEquivariant Quantum Schubert Calculus
We study the T−equivariant quantum cohomology of the Grassmannian. We prove the vanishing of a certain class of equivariant quantum Littlewood-Richardson coefficients, which implies an equivariant quantum Pieri rule. As in the equivariant case, this implies an algorithm to compute the equivariant quantum Littlewood-Richardson coefficients.
متن کاملContemporary Schubert Calculus and Schubert Geometry
Schubert calculus refers to the calculus of enumerative geometry, which is the art of counting geometric figures determined by given incidence conditions. For example, how many lines in projective 3-space meet four given lines? This was developed in the 19th century and presented in the classic treatise ”Kälkul der abzählanden Geometrie” by Herman Cäser Hannibal Schubert in 1879. Schubert, Pier...
متن کاملEigenvalues and Schubert Calculus
We describe recent work of Klyachko, Totaro, Knutson, and Tao, that characterizes eigenvalues of sums of Hermitian matrices, and decomposition of tensor products of representations of GLn(C). We explain related applications to invariant factors of products of matrices, intersections in Grassmann varieties, and singular values of sums and products of arbitrary matrices.
متن کاملEquivariant Schubert Calculus
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 e...
