This is not obvious in general, since the energy associated to the linear equation is not positive. The proof relies essentially on two arguments: global in time Strichartz estimates, and a refined analysis of the linear equation, which makes it possible to use continuity arguments and to control the nonlinear effects.", "revisions": [ { "version": "v2", "updated": "2005-02-18T09:31:31.000Z" } ], "analyses": { "subjects": [ "35Q55", "35A05", "35B30", "35B35" ], "keywords": [ "nonlinear schrodinger equations", "global existence results", "quadratic potentials", "linear equation", "finite time blow" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......5197C" } } }
