Our proof can apply to arbitrary 2+1-dimensional abelian as well as nonabelian gauge theories without a bare Chern-Simons coupling, including any non-renormalizable interactions and non-minimal couplings. Our proof reveals that small (but not large) gauge invariance is enough to ensure the absence of higher order corrections.", "revisions": [ { "version": "v3", "updated": "2000-02-05T06:02:28.000Z" } ], "analyses": { "keywords": [ "simple proof", "non-renormalization", "nonabelian gauge theories", "higher order corrections", "wilsonian effective action" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "inspire": 509121 } } }
