We obtain an upper bound for the solution in terms of a weighted control in $L^p$. This upper bound is applied to the homogeneous Landau equation with moderately soft potentials. We obtain an estimate in $L^\\infty(\\mathbb R^d)$ for the solution of the Landau equation, for positive time, which depends only on the mass, energy and entropy of the initial data.", "revisions": [ { "version": "v1", "updated": "2015-11-10T20:09:00.000Z" } ], "analyses": { "subjects": [ "35B45" ], "keywords": [ "upper bound", "parabolic equation", "right hand side", "power nonlinearity", "nondivergence form" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
