First, we deduce from a result by Jones a quantitative estimate of how far the level sets of solutions are from being spherical. Next, using this property, we derive a criterion providing solutions whose level sets do not converge to spheres for a class of equations including linear equations and Fisher-KPP reaction-diffusion equations.", "revisions": [ { "version": "v1", "updated": "2016-04-13T15:20:28.000Z" } ], "analyses": { "subjects": [ "35K10", "35B06", "35B40" ], "keywords": [ "parabolic equations", "level sets", "fisher-kpp reaction-diffusion equations", "linear equations", "anti-symmetrization properties" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
