Godefroy and the second author of this note proved in 1988 that in duals to Asplund spaces there always exists a projectional resolution of the identity. A few years later, Ch. Stegall succeeded to drop from the original proof a deep lemma of S. Simons. Here, we rewrite the condensed argument of Ch. Stegall in a more transparent and detailed way. We actually show that this technology of Ch. Stegall leads to a bit stronger/richer object ---the so called projectional skeleton--- recently constructed by W. Kubi\\'s, via S. Simons' lemma and with help of elementary submodels from logic.", "revisions": [ { "version": "v1", "updated": "2013-04-04T10:48:27.000Z" } ], "analyses": { "keywords": [ "asplund spaces", "projections", "bit stronger/richer object", "projectional resolution", "original proof" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1304.1313C" } } }
