Polynomials for symmetric orbit closures in the flag variety
Benjamin J. Wyser, Alexander Yong
In [Wyser-Yong '13] we introduced polynomial representatives of cohomology classes of orbit closures in the flag variety, for the symmetric pair . We…
Polynomials for GL_p x GL_q orbit closures in the flag variety
Benjamin J. Wyser, Alexander Yong
The subgroup K=GL_p x GL_q of GL_{p+q} acts on the (complex) flag variety GL_{p+q}/B with finitely many orbits. We introduce a family of polynomials that specializes to representat…
Some conjectures regarding certain Schubert structure constants in Lie types B and D
Benjamin J. Wyser
I give the details of some conjectures regarding Schubert calculus in Lie types B and D. Specifically, I conjecture rules for Schubert structure constants when $X_{w_0u…
K-orbit closures on G/B as universal degeneracy loci for flagged vector bundles splitting as direct sums
Benjamin J. Wyser
We use equivariant localization and divided difference operators to determine formulas for the torus-equivariant fundamental cohomology classes of -orbit closures on the flag va…
