One is the equation of the Hartree type, and the other one is the equation with power nonlinearity. We show that the scattering operator for the equation of the Hartree type converges to that for the one with power nonlinearity in some sense. Our proof is based on some inequalities in the Lorentz space, and a strong limit of Riesz potentials.Department of Mathematics, Hokkaido UniversityDepartmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/69594info:doi/10.14943/83936https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69594/1/pre786.pdfHokkaido University Preprint Series in Mathematics7861132006engpublisher
