The space is defined on the base on a boundedly modified mixed Tsirelson space with use of a special coding function.", "revisions": [ { "version": "v2", "updated": "2013-03-29T06:52:13.000Z" } ], "analyses": { "subjects": [ "46B03" ], "keywords": [ "unconditional basis", "gowers classification program", "ferenczi-rosendal list", "special coding function", "reflexive banach space" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1303.2370M" } } }
