We first define renormalizations and Feynman measures, and show that although there need not exist a canonical Feynman measure, there is a canonical orbit of Feynman measures under renormalization. We then construct a perturbative quantum field theory from a Lagrangian and a Feynman measure, and show that it satisfies perturbative analogues of the Wightman axioms, extended to allow time-ordered composite operators over curved spacetimes.", "revisions": [ { "version": "v2", "updated": "2011-03-09T21:19:22.000Z" } ], "analyses": { "subjects": [ "81T15" ], "keywords": [ "perturbative quantum field theory", "first define renormalizations", "lagrangian", "canonical feynman measure", "satisfies perturbative analogues" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 30, "language": "en", "license": "arXiv", "status": "editable", "inspire": 864332, "adsabs": "2010arXiv1008.0129B" } } }
