As a consequence of the main result, a simple and direct proof for several older results is also included.", "revisions": [ { "version": "v1", "updated": "2007-11-10T22:03:53.000Z" } ], "analyses": { "subjects": [ "46H20", "46H25" ], "keywords": [ "arens regularity", "second adjoit", "derivation", "dual banach module", "banach module actions" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0711.1621M" } } }
