We prove that certain geometric structures of a general nonmonotone flux function ensure the existence of infinitely many Lipschitz solutions to the diffusion equation. Relevant structures are characterized by certain bounded open sets satisfying the so-called chord condition and sufficient conditions for such sets are also given. Our method relies on a modification of the convex integration and Baire's category methods.", "revisions": [ { "version": "v1", "updated": "2018-04-20T14:02:37.000Z" } ], "analyses": { "subjects": [ "35M10", "35K55", "35D30", "49J45", "49K21" ], "keywords": [ "convex integration", "general nonmonotone flux function ensure", "nonmonotone diffusion flux", "general diffusion equations", "baires category methods" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
