We introduce a formal approach which seems to be useful in the study of those properties of operators on $X$ which depend only on the norms of images of elements. This approach is applied to the Daugavet equation for norms of operators; in particular we develop a general theory of narrow operators and rich subspaces of $X$ previously studied in the context of the classical spaces $C(K)$ and $L_1(\\mu)$.", "revisions": [ { "version": "v2", "updated": "2001-03-22T13:24:44.000Z" } ], "analyses": { "subjects": [ "46B20", "46B04", "47B38" ], "keywords": [ "narrow operators", "rich subspaces", "banach space", "daugavet property", "general theory" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2000math......5278K" } } }
