We use this fact to clarify some controversial results appeared in the literature about the value of the central charge in these models.", "revisions": [ { "version": "v3", "updated": "2000-05-11T13:57:53.000Z" } ], "analyses": { "subjects": [ "04.70.Dy", "04.50.+h" ], "keywords": [ "central charge", "symmetry breaking", "two-dimensional anti-de sitter space", "correspondence", "non-constant dilaton" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 524470 } } }
