Moreover, we get the corresponding local well-posed result for semilinear wave equation. The required index of regularity here is 1/4 less than the index 7/4, which is essentially sharp in general.", "revisions": [ { "version": "v1", "updated": "2007-05-20T05:57:06.000Z" } ], "analyses": { "subjects": [ "35L15", "35L70" ], "keywords": [ "nonlinear wave equation", "radial data", "second order quasilinear wave equation", "dimensions", "semilinear wave equation" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007arXiv0705.2849W" } } }
