L2(R) is believed to be a borderline space for the local well-posedness theory of this equation. In the periodic case, Molinet [27] has recently proved that the flow map of the Benjamin-Ono equation is not weakly continuous in L2(T). Our results are in line with previous work on the cubic nonlinear Schrodinger equation, where Goubet and Molinet [11] showed weak continuity in L2(R) and Molinet [28] showed lack of weak continuity in L2(T).", "revisions": [ { "version": "v2", "updated": "2009-10-08T04:20:53.000Z" } ], "analyses": { "subjects": [ "35L70" ], "keywords": [ "benjamin-ono equation", "flow map", "cubic nonlinear schrodinger equation", "local well-posedness theory", "periodic case" ], "note": { "typesetting": "TeX", "pages": 34, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0909.0793C" } } }
