We show that G^00/G^000 is naturally the quotient of a connected compact commutative Lie group by a dense finitely generated subgroup. We also highlight the role of universal covers of semisimple Lie groups.", "revisions": [ { "version": "v1", "updated": "2011-06-17T11:04:31.000Z" } ], "analyses": { "subjects": [ "22F99" ], "keywords": [ "connected components", "definable groups", "o-minimality", "semisimple lie groups", "connected compact commutative lie group" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1106.3442C" } } }
