We discuss the failure of this result in positive characteristic.", "revisions": [ { "version": "v1", "updated": "2013-08-31T17:06:01.000Z" } ], "analyses": { "subjects": [ "13B02" ], "keywords": [ "characteristic zero", "ramification", "regular algebraic local rings", "arbitrary ground fields", "graded rings" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1309.0135C" } } }
