Applications of the Modified Double Sub Equation Method to Nonlinear Partial Differential Equations

In this paper, the modified double sub-equation method is proposed to construct complexiton solutions of nonlinear partial differential equations (PDEs). By means of this method, some new complexiton solutions to nonlinear PDEs are obtained, which are non-travelling wave and variable-coefficient function solutions. It is shown that the modified double sub-equation method is effective and straightforward tool to solve nonlinear PDEs.
