The bifurcation and exact travelling wave solutions of (1+2)-dimensional nonlinear Schr?dinger equation with dual-power law nonlinearity

摘要

By using the method of dynamical systems, this paper researches the bifurcation and the exact traveling wave solutions for a (1+2)-dimensional nonlinear Schr?dinger equation with dual-power law nonlinearity. Exact parametric representations of all wave solutions are given.
