Nonlinear Gauge Transformations and Exact Solutions of the Doebner-Goldin Equation
P. Nattermann, W. Scherer
Abstract
Invariants of nonlinear gauge transformations of a family of nonlinear Schrödinger equations proposed by Doebner and Goldin are used to characterize the behaviour of exact solutions of these equations.
