Our approach depends on majorization techniques. We also consider some perturbation problems, where a positive perturbation of the frame operator of a set of vectors is realized as the frame operator of a set of vectors which is close to the original one.", "revisions": [ { "version": "v1", "updated": "2007-10-05T15:58:34.000Z" } ], "analyses": { "subjects": [ "42C15" ], "keywords": [ "frame operator", "convex functionals", "minimization", "finite dimensional hilbert space", "benedetto-fickus frame potential" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0710.1258M" } } }
