We prove that a 2-contractive representation of a logmodular algebra extends to a positive map on the enveloping C*-algebra, which we show generalizes a result of Foias and Suciu on uniform logmodular algebras. Our proof uses non-commutative operator space generalizations of classical results on 2-summing maps and semispectral measures. We establish some matrix factorization results for uniform logmodular algebras", "revisions": [ { "version": "v2", "updated": "2010-03-23T17:06:26.000Z" } ], "analyses": { "subjects": [ "47L55", "47A67", "47A20" ], "keywords": [ "representation", "uniform logmodular algebras", "logmodular algebra extends", "matrix factorization results", "non-commutative operator space generalizations" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0806.0284P" } } }
