The proof is based upon a sharp estimate on the relative entropy of the law of the process with respect to product reference measures associated to the hydrodynamic limit profile, which holds in any dimension and is of independent interest. As a corollary of this entropy estimate, we obtain some quantitative bounds on the speed of convergence of the aforementioned hydrodynamic limit.", "revisions": [ { "version": "v1", "updated": "2018-10-22T20:13:37.000Z" } ], "analyses": { "subjects": [ "60K35", "60J27", "82C20", "82C22" ], "keywords": [ "interacting particle systems", "non-equilibrium fluctuations", "hydrodynamic limit", "product reference measures", "weakly asymmetric exclusion process" ], "note": { "typesetting": "TeX", "pages": 66, "language": "en", "license": "arXiv", "status": "editable" } } }
