The maximal ones are in a bijective correspondence with the pairs of A-D-E Dynkin diagrams with the difference of their Coxeter numbers equal to 1. In our previous classification of one-dimensional local conformal nets, Dynkin diagrams D_{2n+1} and E_7 do not appear, but now they do appear in this classification of two-dimensional local conformal nets. Such nets are also characterized as two-dimensional local conformal nets with mu-index equal to 1 and central charge less than 1. Our main tool, in addition to our previous classification results for one-dimensional nets, is 2-cohomology vanishing for certain tensor categories related to the Virasoro tensor categories with central charge less than 1.", "revisions": [ { "version": "v1", "updated": "2003-04-14T15:16:39.000Z" } ], "analyses": { "subjects": [ "81T05", "81T40", "46L60", "18D10" ], "keywords": [ "classification", "central charge", "one-dimensional local conformal nets", "classify two-dimensional local conformal nets", "virasoro tensor categories" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer", "journal": "Communications in Mathematical Physics", "year": 2004, "month": "Jan", "volume": 244, "number": 1, "pages": 63 }, "note": { "typesetting": "LaTeX", "pages": 40, "language": "en", "license": "arXiv", "status": "editable", "inspire": 616945, "adsabs": "2004CMaPh.244...63K" } } }
