    A $t$-generalization for Schubert Representatives of the Affine Grassmannian by Avinash J. Dalal, Jennifer Morse

    Published 2013-01-01
    “…We introduce two families of symmetric functions with an extra parameter $t$ that specialize to Schubert representatives for cohomology and homology of the affine Grassmannian when $t=1$. The families are defined by a statistic on combinatorial objects associated to the type-$A$ affine Weyl group and their transition matrix with Hall-Littlewood polynomials is $t$-positive. …”

    The ABC's of affine Grassmannians and Hall-Littlewood polynomials by Avinash J. Dalal, Jennifer Morse

    Published 2012-01-01
    “…In doing so, we prove a new combinatorial formula for representatives of the Schubert classes for the cohomology of affine Grassmannians. We show how new combinatorics involved in our formulas gives the Kostka-Foulkes polynomials and discuss how this can be applied to study the transition matrices between Hall-Littlewood and $k$-Schur functions.…”
