The Functional Expansion Approach for Solving NPDEs as a Generalization of the Kudryashov and G′/G Methods

Symmetry, 2022
This paper presents the functional expansion approach as a generalized method for finding traveling wave solutions of various nonlinear partial differential equations. The approach can be seen as a combination of the Kudryashov and G′/G solving methods. It allowed the extension of the first method to the use of second order auxiliary equations, and, at
