On Ideal Generators for Affine Schubert Varieties
V. Kreiman, V. Lakshmibai, P. Magyar +1
We consider a certain class of Schubert varieties of the affine Grassmannian of type A. By embedding a Schubert variety into a finite-dimensional Grassmannian, we construct an expl…
Standard Bases for Affine SL(n)-Modules
V. Kreiman, V. Lakshmibai, P. Magyar +1
We give an elementary and easily computable basis for the Demazure modules in the basic representation of the affine Lie algebra sl(n)-hat (and the loop group SL(n)-hat). A novel f…
Richardson Varieties in the Grassmannian
Victor Kreiman, V. Lakshmibai
The Richardson variety is defined to be the intersection of the Schubert variety and the opposite Schubert variety . For in the Grassmannian, we obtain a…
Multiplicities of Singular Points in Schubert Varieties of Grassmannians
V. Kreiman, V. Lakshmibai
We give a closed-form formula for the Hilbert function of the tangent cone at the identity of a Schubert variety X in the Grassmannian in both group theoretic and combinatorial ter…
