For instance, we show that such a remainder is Hurewicz if and only it it is $\\sigma$-compact. Also, the existence of a Scheepers non-$\\sigma$-compact remainder of a topological group follows from CH and yields a $P$-point, and hence is independent of ZFC. We also make an attempt to prove a dichotomy for the Menger property of remainders of topological groups in the style of Arhangel'skii.", "revisions": [ { "version": "v1", "updated": "2015-04-07T14:47:01.000Z" } ], "analyses": { "subjects": [ "03E75", "54D40", "54D20", "03E35", "54D30", "54D80" ], "keywords": [ "topological group", "menger remainders", "constrains combinatorial covering properties", "hurewicz impose", "compact remainder" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150401626B" } } }
