This extends results obtained in [4] for the equation div u = f , improving them on two aspects: one works here with the divergence equation with measure data, and also construct a weight w that relies in a softer way on the geometry of $\\Omega$, improving its behavior (and hence the a priori behavior of the solution we construct) substantially in some instances. The method used in this paper follows a constructive approach of Bogovskii type.", "revisions": [ { "version": "v1", "updated": "2020-03-16T15:03:33.000Z" } ], "analyses": { "keywords": [ "weighted lebesgue spaces", "divergence equation", "measure data", "solvability", "bogovskii type" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
