The Iwahori-Hecke algebra H k (q 2 ) of type A acts on tensor product space V ⊗k of the natural representation of the quantum superalgebra Uq(gl(m, n)). We show this action of H k (q 2 ) and the action of Uq(gl(m, n)) on the same space determine commuting actions of each other. Together with this result and Gyoja's q-analogue of the Young symmetrizer, we construct a highest weight vector of each irreducible summmand of the tensor product space V ⊗k , for k = 1, 2, . . . .
We establish a connection between planar rook algebras and tensor representations V ⊗k of the natural two-dimensional representation V of the general linear Lie superalgebra gl(1|1). In particular, we show that the centralizer algebra End gl(1|1) (V ⊗k ) is the planar rook algebra CP k−1 for all k ≥ 1, and we exhibit an explicit decomposition of V ⊗k into irreducible gl(1|1)-modules. We obtain similar results for the quantum enveloping algebra U q (gl(1|1)) and its natural two-dimensional module V q .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
