A Green's function for a linear equation associated with solitons

J. P. Keener, D. W. McLaughlin

Research output: Contribution to journalArticlepeer-review


A linear equation associated with nonlinear wave equations which support solitons is analyzed. A complete set of solutions of this linear equation is described through the techniques of scattering theory. This set is used to construct an explicit representation of a Green's function for perturbation theory. The cases of the nonlinear Schrödinger and sine-Gordon equations are discussed in some detail.
