Abstract:The Exp-function method plays an important role in searching for analytic solutions of many nonlinear differential equations. In this paper, we prove that the balancing procedure in the method is unnecessary when the balanced nonlinear term is a product of the dependent variable under consideration and its derivatives. And in this case, the ansatz of the method can be simplified to be with less parameters so as to be easy to calculate.
“…By some mathematical software, the solution process is extremely simple and abundant solutions are predicted [19][20][21]. The exp-function method is a universal tool for nonlinear equations and can be easily extended to fractional calculus [22][23][24][25][26][27].…”
This paper elucidates the main advantages of the exp-function method in finding exact solutions of nonlinear wave equations. By the aid of some mathematical software, the solution process becomes extremely simple and accessible.
