Tensor decomposition of Demazure crystals for symmetrizable Kac-Moody Lie algebras

Divya Setia

We study the tensor product of Demazure crystals for symmetrizable Kac-Moody Lie algebras. It is not necessary that the tensor product of Demazure crystals is isomorphic to a disjo…

Graded representations of current Lie superalgebras $sl (1∣2) [t]$

Shushma Rani, Divya Setia

This paper is the study of finite-dimensional graded representations of current lie superalgebras $sl (1∣2) [t]$ . We define the notion of super POPs, a combinatorial tool…

Filtration of tensor product of local Weyl modules for $sl_{n + 1} [t]$

Divya Setia, Shushma Rani, Tanusree Khandai

In this paper, we consider the tensor product of local Weyl modules for $sl_{n + 1} [t]$ whose highest weights are multiples of the first and $n^{t h}$ fundamental weights.…
