The same result also holds for the pair $(c_0, Y)$ for any uniformly monotone Banach lattice $Y.$ Further we show that these results are optimal in case that $Y$ is strictly monotone.", "revisions": [ { "version": "v1", "updated": "2019-07-19T09:53:10.000Z" } ], "analyses": { "subjects": [ "46B04", "47B99" ], "keywords": [ "positive operators", "bishop-phelps-bollobás property", "uniformly monotone banach lattice", "weak unit", "bishop-phelps-bollobas property" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
