Exact Solutions of (2+1)-Dimensional Nonlinear Schrödinger Equation Based on Modified Extended Tanh Method

Abstract

In this paper, the modified extended tanh method is used to construct more general exact solutions of a (2+1)-dimensional nonlinear Schrödinger equation. With the aid of Maple and Matlab software, we obtain exact explicit kink wave solutions, peakon wave solutions, periodic wave solutions and their 3D images.
