The resulting U(N) Yang-Mills theory on R^d_C is equivalent to that obtained by the dimensional reduction of (d+2n)-dimensional U(N) Yang-Mills theory onto R^d_C. We show that the gauge-Higgs system (A_\\mu,\\Phi^a) in the U(N -> \\infty) Yang-Mills theory on R^d_C leads to an emergent geometry in the (d+2n)-dimensional spacetime whose metric was determined by Ward a long time ago. In particular, the 10-dimensional gravity for d=4 and n=3 corresponds to the emergent geometry arising from the 4-dimensional N=4 vector multiplet in the AdS/CFT duality. We further elucidate the emergent gravity by showing that the gauge-Higgs system (A_\\mu,\\Phi^a) in half-BPS configurations describes self-dual Einstein gravity.", "revisions": [ { "version": "v3", "updated": "2009-08-03T02:53:10.000Z" } ], "analyses": { "subjects": [ "02.40.Gh", "04.50.+h", "11.10.Nx" ], "keywords": [ "gauge theory", "yang-mills theory", "noncommutative electromagnetism", "emergent geometry", "gauge-higgs system" ], "tags": [ "journal article" ], "publication": { "journal": "European Physical Journal C", "year": 2009, "month": "Dec", "volume": 64, "number": 3, "pages": 445 }, "note": { "typesetting": "TeX", "pages": 25, "language": "en", "license": "arXiv", "status": "editable", "inspire": 748197, "adsabs": "2009EPJC...64..445Y" } } }
