In combination with known automatic continuity results, this implies that the compact-open topology is the unique Hausdorff separable group topology on the group if the surface is closed or the complement in a closed surface of either a finite set or the union of a finite set and a Cantor set.", "revisions": [ { "version": "v1", "updated": "2022-10-31T13:02:59.000Z" } ], "analyses": { "subjects": [ "57S05", "57N99" ], "keywords": [ "homeomorphism group", "compact-open topology", "finite set", "unique hausdorff separable group topology", "hausdorff group topology strictly coarser" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
