This modification is equivalent to normal ordering the $\\phi^4$ vertex. In the limit of the commutative sphere, the perturbation theory of this modified action matches that of the commutative theory.", "revisions": [ { "version": "v1", "updated": "2001-09-11T22:13:40.000Z" } ], "analyses": { "keywords": [ "fuzzy sphere", "continuum limits", "uv/ir mixing problems", "perturbation theory", "modified action matches" ], "tags": [ "journal article" ], "publication": { "publisher": "IOP", "journal": "Journal of High Energy Physics", "year": 2002, "month": "Mar", "volume": 2002, "number": 3, "pages": "013" }, "note": { "typesetting": "LaTeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "inspire": 562633, "adsabs": "2002JHEP...03..013D" } } }
