The results include: (1) If Two has a winning strategy in the Menger game on a regular space X, then X is an Alster space. (2) If Two has a winning strategy in the Rothberger game on a topological space X, then the G_\\delta-topology on X is Lindelof. (3) The Menger game and the compact-open game are (consistently) not dual.", "revisions": [ { "version": "v2", "updated": "2013-06-27T13:26:49.000Z" } ], "analyses": { "subjects": [ "54D20", "54G99", "54A10" ], "keywords": [ "alster space", "topological games", "menger game", "winning strategy", "study connections" ], "note": { "typesetting": "TeX", "pages": 13, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1306.5463A" } } }
