We study the restriction of global and local Weyl modules of current algebras to this Levi subalgebra. We identify necessary and sufficient conditions on a pair of a Levi subalgebra and a dominant integral weight, such that the restricted module is a global (resp. a local) Weyl module.", "revisions": [ { "version": "v3", "updated": "2013-11-11T16:18:42.000Z" } ], "analyses": { "subjects": [ "17B10", "17B67" ], "keywords": [ "simple complex lie algebra", "local weyl modules", "dominant integral weight", "simple levi subalgebras", "finite rank" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1212.6505F" } } }
