Because of the mass-deformation, a vacuum geometry turns out to be a constant curvature spacetime such as d-dimensional sphere and (anti-)de Sitter spaces. We show that the mass-deformed matrix model giving rise to the constant curvature spacetime can be derived from the d-dimensional Snyder algebra. The emergent geometry beautifully confirms all the rationale inferred from the algebraic point of view that the d-dimensional Snyder algebra is equivalent to the Lorentz algebra in (d+1)-dimensional {\\it flat} spacetime. For example, a vacuum geometry of the mass-deformed matrix model is completely described by a G-invariant metric of coset manifolds G/H defined by the Snyder algebra. We also discuss a nonlinear deformation of the Snyder algebra.", "revisions": [ { "version": "v4", "updated": "2010-08-05T03:41:28.000Z" } ], "analyses": { "subjects": [ "02.40.Gh", "11.25.Tq", "11.10.Nx" ], "keywords": [ "emergent geometry", "mass-deformed matrix model", "quantized spacetime", "matrix model giving rise", "d-dimensional snyder algebra" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review D", "year": 2010, "month": "Aug", "volume": 82, "number": 4, "pages": "045004" }, "note": { "typesetting": "TeX", "pages": 33, "language": "en", "license": "arXiv", "status": "editable", "inspire": 829142, "adsabs": "2010PhRvD..82d5004Y" } } }
