The novelty of the analysis lies in the construction of suitable relaxation systems and the derivation of a delicate estimate on the relative entropy. We provide a direct proof of convergence in the smooth regime for a wide class of physical systems. We present results for systems arising in materials science, where the presence of source terms presents a number of additional challenges and requires delicate treatment. Our analysis is in the spirit of the framework introduced by Tzavaras [A. Tzavaras, Commun. Math. Sci., 3-2, 2005] for systems of hyperbolic conservation laws.", "revisions": [ { "version": "v1", "updated": "2014-08-04T20:50:30.000Z" } ], "analyses": { "subjects": [ "35B35", "76N10" ], "keywords": [ "relative entropy", "hyperbolic relaxation", "hyperbolic conservation laws", "hyperbolic balance laws", "general framework" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1408.0815M" } } }
