Schubert calculus of Richardson varieties stable under spherical Levi subgroups
Benjamin J. Wyser
We observe that the expansion in the basis of Schubert cycles for of the class of a Richardson variety stable under a spherical Levi subgroup is described by a theorem o…

K-orbit closures on G/B as universal degeneracy loci for flagged vector bundles with symmetric or skew-symmetric bilinear form
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…

Symmetric subgroup orbit closures on flag varieties: Their equivariant geometry, combinatorics, and connections with degeneracy loci
Benjamin J. Wyser
We give explicit formulas for torus-equivariant fundamental classes of closed -orbits on the flag variety when is one of the classical groups $SL(n,\C)$, $SO(n,\C)$, o…
