Abstract
By a series of transformations, the (2+1)-dimensional variable coefficient nonlinear Schrödinger equation can turn to the Klein–Gordon equation. Many new double travelling wave solutions of the Klein–Gordon equation are obtained. Thus, the new solitary solutions of the variable coefficient nonlinear Schrödinger equation with an external potential can be found.
