Voiculescu [2] proved that a standard family of independent random unitary k by k matrices and a constant k by k unitary matrix is asymtotically free as k goes to infinity. This result was a key ingredient in Voiculescu's proof [3] that his free entropy is additive when the variables are free. In this paper, we give a very elementary proof of a more detailed version of this result [2].", "revisions": [ { "version": "v1", "updated": "2008-02-03T19:56:12.000Z" } ], "analyses": { "subjects": [ "46L10" ], "keywords": [ "voiculescus free entropy", "elementary proof", "free-additivity", "independent random unitary", "unitary matrix" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0802.0292H" } } }
