Equivariant Giambelli and determinantal restriction formulas for the Grassmannian
V. Lakshmibai, K. N. Raghavan, P. Sankaran
The main result of the paper is a determinantal formula for the restriction to a torus fixed point of the equivariant class of a Schubert subvariety in the torus equivariant integr…
Picture invariants and the isomorphism problem for complex semisimple Lie algebras
Vijay Kodiyalam, K. N. Raghavan
Consider complex semisimple Lie algebras of a given dimension specified by their structure constants. We describe a finite collection of rational functions in the structure constan…
Cohen-Macaulay fiber cones
Clare D'Cruz, K. N. Raghavan, J. K. Verma
Cohen Macaulay property of fiber cones of ideals is characterized in terms of its Hilbert series. Hilbert series of fiber cones of ideals with minimal mixed multiplicity is calcula…
Hilbert functions of points on Schubert varieties in the Grassmannian
Vijay Kodiyalam, K. N. Raghavan
We prove a recent conjecture of Kreiman and Lakshmibai about Hilbert functions of points on Schubert varieties in Grassmannians.
