The formula implies the boundedness of wave operators on L^p spaces, 1 \\leq p \\leq \\infty, on weighted L^p spaces, and on Sobolev spaces, as well as multilinear estimates for e^{itH} P_c. When V decreases rapidly at infinity, we obtain an asymptotic expansion of the wave operators. The first term of the expansion is of order < y >^{-4}, commutes with the Laplacian, and exists when V \\in ^{-3/2-\\epsilon} L^2. We also prove that the scattering operator S = W_-^* W_+ is an integrable combination of isometries. The proof is based on an abstract version of Wiener's theorem, applied in a new function space.", "revisions": [ { "version": "v3", "updated": "2012-04-20T01:20:11.000Z" } ], "analyses": { "subjects": [ "35P25", "35J10", "47A40", "47F05", "47N50", "81U40", "35C20" ], "keywords": [ "wave operators", "asymptotic expansion", "scalar potentials", "formula implies", "sobolev spaces" ], "note": { "typesetting": "TeX", "pages": 49, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1101.0502B" } } }
