Full toroidal Lie algebra is the semidirect product of derived Lie algebra of toroidal Lie algebra and Witt algebra, also it can be thought of $n$-variable generalization of Affine-Virasoro algebras. Let $\\tilde{\\mathfrak{h}}$ be a Cartan subalgebra of a toroidal Lie algebra as well as full toroidal Lie algebra without containing the zero-degree central elements. In this paper, we classify the module structure on $U(\\tilde{\\mathfrak{h}})$ for all toroidal Lie algebras as well as full toroidal Lie algebras which are free $U(\\tilde{\\mathfrak{h}})$-modules of rank 1. These modules exist only for type $A_l (l\\geq 1)$, $C_l (l\\geq2)$ toroidal Lie algebras and the same is true for full toroidal Lie algebras. Also, we determined the irreducibility condition for these classes of modules for both the Lie algebras.", "revisions": [ { "version": "v1", "updated": "2023-12-11T12:15:51.000Z" } ], "analyses": { "subjects": [ "17B65", "17B66", "17B68" ], "keywords": [ "full toroidal lie algebra", "polynomial algebras", "affine kac-moody lie algebras", "representations", "zero-degree central elements" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
