In addition, we propose a simple, at most two step, selection procedure to identify a unique semigroup solution in the class of dissipative solutions to the Euler system. Finally, we introduce a refined version of Dafermos' criterion yielding a unique solution of the problem for any finite energy initial data.", "revisions": [ { "version": "v1", "updated": "2025-01-09T10:35:20.000Z" } ], "analyses": { "subjects": [ "35Q31", "76N10", "35B65", "35D99", "35F50" ], "keywords": [ "dissipative solutions", "gas dynamics", "regularity", "well-posedness", "finite energy initial data" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
