The same result has already been obtained for the groups of the infinite series and for some special cases of exceptional groups.", "revisions": [ { "version": "v2", "updated": "2008-08-12T15:55:25.000Z" } ], "analyses": { "subjects": [ "20C08" ], "keywords": [ "cyclotomic hecke algebras", "schur elements", "exceptional complex reflection groups", "remain constant", "weyl groups" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0802.4306C" } } }
