Our first result is the well-posedness for this problem: We show existence and uniqueness of a (local in time) mild solution. The main result is about blow-up of said solution, and in particular we find sufficient conditions on the initial datum and on the term b to ensure blow-up of the solution in finite time.", "revisions": [ { "version": "v1", "updated": "2020-07-09T06:55:59.000Z" } ], "analyses": { "keywords": [ "nonlinear pde", "fractional laplacian operator", "initial datum", "sufficient conditions", "finite time" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
