In this paper we survey known results on Piotrowski spaces and investigate the relation of Piotrowski spaces to strictly fragmentable, Stegall, and game determined spaces. Also we prove that a Piotrowski Tychonoff space $X$ contains a dense (completely) metrizable Baire subspace if and only if $X$ is Baire (Choquet).", "revisions": [ { "version": "v1", "updated": "2016-09-18T12:41:20.000Z" } ], "analyses": { "subjects": [ "54C08", "54E18", "54E35", "54E52" ], "keywords": [ "piotrowski spaces", "quasicontinuous functions", "piotrowski tychonoff space", "baire space", "game determined spaces" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
