It is based on the naturally associated affine group $G$, a smooth subalgebra of $C^*(G)$, and an operator $\\caD$ defined by two derivations on this subalgebra. While $\\caD$ has metric dimension two, the spectral dimension of the triple is one. This bypasses an obstruction described in \\cite{IochMassSchu11a} on existence of finitely-summable spectral triples for a compactified $\\kappa$-deformation.", "revisions": [ { "version": "v1", "updated": "2012-08-06T11:49:16.000Z" } ], "analyses": { "keywords": [ "deformation", "regular spectral triple", "spectral dimension", "metric dimension", "associated affine group" ], "note": { "typesetting": "TeX", "pages": 29, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1126011, "adsabs": "2012arXiv1208.1140I" } } }
