These properties appear to be close to so-called selection principles, which permits us to show, that (it is consistent with ZFC that) the property of Hurewicz (Menger) is l-invariant. This gives a method of construction of OF-undetermined topological groups with strong combinatorial properties.", "revisions": [ { "version": "v1", "updated": "2005-09-26T04:42:07.000Z" } ], "analyses": { "keywords": [ "tychonoff space", "free objects", "o-boundedness", "free locally-convex linear topological space", "topological group" ], "note": { "typesetting": "LaTeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......9607Z" } } }
