Under some assumptions we prove that such solutions exist at least for propagation speeds c {\\in}]c*, +{\\infty}, where c* > 0 is explicitly computed but may not be optimal. We also prove that a free boundary hy- persurface separates a region where u = 0 and a region where u > 0, and that this free boundary can be globally parametrized as a Lipschitz continuous graph under some additional non-degeneracy hypothesis; we investigate solutions which are, in the region u > 0, planar and linear at infinity in the propagation direction, with slope equal to the propagation speed.", "revisions": [ { "version": "v1", "updated": "2012-01-24T07:55:11.000Z" } ], "analyses": { "keywords": [ "traveling wave solutions", "advection-diffusion equations", "nonlinear diffusion", "nonlinear parabolic degenerate diffusion equation", "free boundary" ], "note": { "typesetting": "TeX", "pages": 40, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013AnIHP..30..705M" } } }
