Given strictly positive initial values, we show that the solution exists in the maximal $L^{q}$-regularity space for all times and is instantaneously smooth in space and time, where the maximal $L^{q}$-regularity is obtained in the sense of Mellin-Sobolev spaces. Moreover, we obtain precise information concerning the asymptotic behavior of the solution close to the singularity. Finally, we show the existence of generalized solutions for non-negative initial data.", "revisions": [ { "version": "v1", "updated": "2017-08-24T20:20:54.000Z" } ], "analyses": { "subjects": [ "35K59", "35K65", "35R01" ], "keywords": [ "porous medium equation", "long time existence", "singularity", "conical singularities", "smoothness" ], "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable" } } }
