A nontrivial form of the lower bound for the Fisher information measure is derived in presence of a flux vector, which satisfies the continuity equation. We also establish a novel upper bound on the time derivative (production) in terms of the arrow of time and derive a lower bound by the logarithmic Sobolev inequality. These serve as the revealing dynamics of the information content and its limitations pertaining to nonequilibrium processes.", "revisions": [ { "version": "v1", "updated": "2012-04-05T09:23:56.000Z" } ], "analyses": { "subjects": [ "05.70.Ln", "05.70.Ce", "89.70.Cf" ], "keywords": [ "production", "lower bound", "fisher information measure", "novel upper bound", "logarithmic sobolev inequality" ], "tags": [ "journal article" ], "publication": { "publisher": "AIP", "journal": "Journal of Mathematical Physics", "year": 2012, "month": "Apr", "volume": 53, "number": 4, "pages": 3301 }, "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012JMP....53d3301Y" } } }
