Irreducible Integrable Modules for the full Toroidal Lie Algebras co-ordinated by Rational Quantum Torus

preprint2022arXivOpen access

Abstract

Let Cq\mathbb{C}_q be a non-commutative Laurent polynomial ring associated with a (n+1)×(n+1)(n+1)\times (n+1) rational quantum matrix qq. Let sld(Cq)⊕HC1(Cq)\mathfrak{sl}_d(\mathbb{C}_q)\oplus HC_1(\mathbb{C}_q) be the universal central extension of Lie subalgebra sld(Cq)\mathfrak{sl}_d(\mathbb{C}_q) of gld(Cq)\mathfrak{gl}_d(\mathbb{C}_q). Now let us take the Lie algebra τ=gld(Cq)⊕HC1(Cq)τ=\mathfrak{gl}_d(\mathbb{C}_q)\oplus HC_1(\mathbb{C}_q). Let Der(Cq)Der(\mathbb{C}_q) be the Lie algebra of all derivations of Cq\mathbb{C}_q. Now we consider the Lie algebra τ~=τ⋊Der(Cq)\tildeτ=τ\rtimes Der(\mathbb{C}_q), called as full toroidal Lie algebra co-ordinated by rational quantum tori. In this paper we get a classification of irreducible integrable modules with finite dimensional weight spaces for τ~\tildeτ with nonzero central action on the modules.
