We derive a scaling limit of the Hamiltonian of the GSB model independently of whether or not the quantum scalareld has a mass. Applying it to a model for the eld of the nuclear force with isospin, we obtain an effective potential of the interaction between nucleons. Also, we get some applications to condensed matter physics.Department of Mathematics, Hokkaido UniversityDepartmental Bulletin Paperapplication/pdfhttp://hdl.handle.net/2115/69554info:doi/10.14943/83896https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69554/1/pre746.pdfHokkaido University Preprint Series in Mathematics7461212005-10-03engpublisher
