We introduce a variant of their amalgamation technique which provides an isometrically universal space in the case that $ C $ consists of spaces with a monotone Schauder basis. For example, we prove that if $ C $ is a set of separable Banach spaces which is analytic with respect to the Effros-Borel structure and every $ X \\in C $ is reflexive and has a monotone Schauder basis, then there exists a separable reflexive Banach space that is isometrically universal for $ C $.", "revisions": [ { "version": "v1", "updated": "2015-04-26T18:34:41.000Z" } ], "analyses": { "subjects": [ "46B04", "54H05", "46B15", "46B20", "46B70" ], "keywords": [ "monotone basis", "monotone schauder basis", "separable banach spaces", "isomorphically universal space", "isometrically universal space" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150406862K" } } }
