As its applications, a characterization of compact difference is given for composition operators acting on the bounded function spaces.", "revisions": [ { "version": "v1", "updated": "2007-09-10T16:06:46.000Z" } ], "analyses": { "subjects": [ "47B38", "26A16", "32A16", "32A26", "32A37" ], "keywords": [ "bounded function space", "essential norm", "simple estimates", "unit polydiscs", "holomorphic self-maps" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0709.1430F" } } }
