Comments welcome", "categories": [ "math.PR", "math.AP" ], "abstract": "We provide an elementary proof of geometric synchronisation for scalar conservation laws on a domain with Dirichlet boundary conditions. Unlike previous results, our proof does not rely on a strict maximum principle, and builds instead on a quantitative estimate of the dissipation at the boundary. We identify a coercivity condition under which the estimates are uniform over all initial conditions, via the construction of suitable super- and sub-solutions. In lack of such coercivity our results build on Lp energy estimates and a Lyapunov structure.", "revisions": [ { "version": "v1", "updated": "2022-11-10T19:12:12.000Z" } ], "analyses": { "subjects": [ "60H15", "37H15", "37L55", "37A25" ], "keywords": [ "scalar conservation laws", "synchronisation", "dirichlet boundary conditions", "strict maximum principle", "lp energy estimates" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
