Mixed tensor invariants of Lie color algebra
Santosha Pattanayak, Preena Samuel
In this paper, we consider the mixed tensor space of a -graded vector space where is a finite abelian group. We obtain a spanning set of invariants of the associated symmetr…

Graded Picture Invariants and polynomial invariants for mixed tensor superspaces
Santosha Pattanayak, Preena Samuel
In this paper we consider the mixed tensor space of a -graded vector space. We obtain a spanning set of invariants of the associated symmetric algebra under the action…

RSK bases and Kazhdan-Lusztig cells
K. N. Raghavan, Preena Samuel, K. V. Subrahmanyam
From the combinatorial characterizations of the right, left, and two-sided Kazhdan-Lusztig cells of the symmetric group, 'RSK bases' are constructed for certain quotients by two-si…
