We show global Holder regularity up to the boundary of the solution, with a method based on the De Giorgi techniques. The boundary introduces several difficulties. In particular, the Dirichlet Laplacian is not translation invariant near the boundary, which leads to complications involving the Riesz transform.", "revisions": [ { "version": "v1", "updated": "2019-06-01T16:10:58.000Z" } ], "analyses": { "subjects": [ "35Q35", "35Q86" ], "keywords": [ "bounded domains", "critical sqg", "global holder regularity", "riesz transform", "dissipative sqg equation" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
