The goal of this paper is to study the category O for W introduced by Brundan, Goodwin and Kleshchev. We establish an equivalence of this category with certain category of g-modules. In the case when e is of principal Levi type (this is always so when g is of type A) the category of g-modules in interest is the category of generalized Whittaker modules introduced McDowel and studied by Milicic-Soergel and Backelin.", "revisions": [ { "version": "v3", "updated": "2009-05-31T14:24:12.000Z" } ], "analyses": { "subjects": [ "17B35" ], "keywords": [ "semisimple lie algebra", "principal levi type", "finite type", "generalized whittaker modules", "nilpotent element" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0812.1584L" } } }
