The main assumption on the potential is that it grows at most quadratically in space, uniformly with respect to the time variable. We show a general exponential control of first order derivatives and momenta, which yields a double exponential bound for higher Sobolev norms and momenta. On the other hand, we show that if the potential is an isotropic harmonic potential with a time dependent frequency which decays sufficiently fast, then Sobolev norms are bounded, and momenta grow at most polynomially in time, because the potential becomes negligible for large time: there is scattering, even though the potential is unbounded in space for fixed time.", "revisions": [ { "version": "v1", "updated": "2013-05-17T14:17:14.000Z" } ], "analyses": { "keywords": [ "large time behavior", "time dependent potential", "time dependent external potential", "sobolev norms", "defocusing nonlinear schrodinger equation" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1305.4089C" } } }
