K-orbit closures and Barbasch-Evens-Magyar varieties
Laura Escobar, Benjamin J. Wyser, Alexander Yong
We define the Barbasch-Evens-Magyar varieties. We show they are isomorphic to the smooth varieties defined in [D.~Barbasch-S.~Evens '94] that map generically finitely to symmetric…
Governing singularities of symmetric orbit closures
Alexander Woo, Benjamin Wyser, Alexander Yong
We develop interval pattern avoidance and Mars-Springer ideals to study singularities of symmetric orbit closures in a flag variety. This paper focuses on the case of the Levi subg…
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…
Wonderful Symmetric Varieties and Schubert Polynomials
Mahir Bilen Can, Michael Joyce, Benjamin Wyser
Extending results of Wyser, we determine formulas for the equivariant cohomology classes of closed orbits of certain families of spherical subgroups of on the flag variety $…
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+…
