Saturation for Flagged Skew Littlewood-Richardson Coefficients
Siddheswar Kundu, K. N. Raghavan, V. Sathish Kumar +1
We define and study a generalization of the Littlewood-Richardson (LR) coefficients, which we call the flagged skew LR coefficients. These subsume several previously studied extens…
The saturation property for refined Littlewood-Richardson coefficients
Mrigendra Singh Kushwaha, K. N. Raghavan, Sankaran Viswanath
Given dominant integral weights of a finite-dimensional simple Lie algebra and an element of its Weyl group, the refined tensor product multiplicity $c…
A study of Kostant-Kumar modules via Littelmann paths
Mrigendra Singh Kushwaha, K N Raghavan, Sankaran Viswanath
We study, by means of Littelmann's theory of paths, Kostant-Kumar modules (KK modules for short), which by definition are certain submodules of the tensor product of two irreducibl…
A relationship between Gelfand-Tsetlin bases and Chari-Loktev bases for irreducible finite dimensional representations of special linear Lie algebras
K N Raghavan, B Ravinder, Sankaran Viswanath
We consider two bases for an arbitrary finite dimensional irreducible representation of a complex special linear Lie algebra: the classical Gelfand-Tsetlin basis and the relatively…
On Chari-Loktev bases for local Weyl modules in type
K. N. Raghavan, B. Ravinder, Sankaran Viswanath
This paper is a study of the bases introduced by Chari-Loktev for local Weyl modules of the current algebra associated to a special linear Lie algebra. Partition overlaid patterns,…
Stability of the Chari-Pressley-Loktev bases for local Weyl modules of
K. N. Raghavan, B. Ravinder, Sankaran Viswanath
We prove stability of the Chari-Pressley-Loktev bases for natural inclusions of local Weyl modules of the current algebra . These modules being known to be Demazure submod…
