Conormal Varieties of covexillary Schubert Varieties

Rahul Singh

A permutation is called covexillary if it avoids the pattern $3412$ . We construct an open embedding of a covexillary matrix Schubert variety into a Grassmannian Schubert variety. A…

A Robinson-Schensted Correspondence for Partial Permutations

Rahul Singh

We study the Steinberg variety associated to matrix Schubert varieties, and develop a Robinson-Schensted type correspondence, $τ \leftrightarrow (Λ, Q, P)$ . Here $τ$ is…

Mather classes and conormal spaces of Schubert varieties in cominuscule spaces

Leonardo C. Mihalcea, Rahul Singh

Let $G / P$ be a complex cominuscule flag manifold. We prove a type independent formula for the torus equivariant Mather class of a Schubert variety in $G / P$ , and for a Schubert vari…
