For this type of properties, we obtain a general reduction theorem, which, roughly speaking, states the following: if the property in question is stable under certain finite absolute sums (for example finite $\\ell^p$-sums), then it is also stable under the formation of corresponding K\\\"othe-Bochner spaces (for example $L^p$-Bochner spaces). From this general theorem, we obtain as corollaries a number of new results as well as some alternative proofs of already known results concerning octahedral and almost square spaces and their relatives, diameter-two-properties, lush spaces and other classes.", "revisions": [ { "version": "v1", "updated": "2017-02-16T17:01:18.000Z" } ], "analyses": { "subjects": [ "46B20", "46E40" ], "keywords": [ "banach spaces", "geometric properties", "vector-valued functions", "general reduction theorem", "finite absolute sums" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
