The Bruhat order on clans
Benjamin J. Wyser
We give an explicit description of the closure containment order (or "Bruhat order") on the set of orbits of GL_p \times GL_q on the flag variety GL_{p+q}/B, relative to the parame…
Chains in Weak Order Posets Associated to Involutions
Mahir Bilen Can, Michael Joyce, Benjamin Wyser
The W-set of an element of a weak order poset is useful in the cohomological study of the closures of spherical subgroups in generalized flag varieties. We explicitly describe in a…
Combinatorial results on (1,2,1,2)-avoiding -orbit closures on
Alexander Woo, Benjamin J. Wyser
Using recent results of the second author which explicitly identify the "-avoiding" -orbit closures on the flag manifold $GL(p+…
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…
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…
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…
