Multiplicity at any torus-fixed point in a Richardson variety in the Symplectic Grassmannian
Papi Ray, Shyamashree Upadhyay
We give a combinatorial description of the multiplicity at any torus fixed point on a Richardson variety in the Symplectic Grassmannian.

Local properties of Schubert Varieties in the Symplectic Grassmannian via a bounded RSK correspondence
Shyamashree Upadhyay, Papi Ray
In a paper by Ghorpade and Raghavan, they provide an explicit combinatorial description of the Hilbert function of the tangent cone at any point on a Schubert variety in the symple…
