Influence of a double continuous spectrum of the Dirac operator on the asymptotic solitons of a nonlinear Schrödinger equation
The nonlinear Schrödinger equation \(iu_ t+U_{xx}+2| u|^ 2u=0\) is considered and the influence of the double continuous spectrum of the Dirac operator corresponding to given solution u(x,t) to the soliton asymptotics of this solution is treated.
