--- res: bibo_abstract: - 'We establish a weak–strong uniqueness principle for solutions to entropy-dissipating reaction–diffusion equations: As long as a strong solution to the reaction–diffusion equation exists, any weak solution and even any renormalized solution must coincide with this strong solution. Our assumptions on the reaction rates are just the entropy condition and local Lipschitz continuity; in particular, we do not impose any growth restrictions on the reaction rates. Therefore, our result applies to any single reversible reaction with mass-action kinetics as well as to systems of reversible reactions with mass-action kinetics satisfying the detailed balance condition. Renormalized solutions are known to exist globally in time for reaction–diffusion equations with entropy-dissipating reaction rates; in contrast, the global-in-time existence of weak solutions is in general still an open problem–even for smooth data–, thereby motivating the study of renormalized solutions. The key ingredient of our result is a careful adjustment of the usual relative entropy functional, whose evolution cannot be controlled properly for weak solutions or renormalized solutions.@eng' bibo_authorlist: - foaf_Person: foaf_givenName: Julian L foaf_name: Fischer, Julian L foaf_surname: Fischer foaf_workInfoHomepage: http://www.librecat.org/personId=2C12A0B0-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-0479-558X bibo_doi: 10.1016/j.na.2017.03.001 bibo_volume: 159 dct_date: 2017^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/0362546X dct_language: eng dct_publisher: Elsevier@ dct_title: Weak–strong uniqueness of solutions to entropy dissipating reaction–diffusion equations@ ...
