Popular Ansatz Methods and Solitary Wave Solutions of the Kuramoto–Sivashinsky Equation
2009, vol. 14, no. 3, pp. 407-419
Some methods to look for exact solutions of nonlinear differential equations are discussed. It is shown that many popular methods are equivalent to each other. Several recent publications with "new" solitary wave solutions for the Kuramoto–Sivashinsky equation are analyzed. We demonstrate that all these solutions coincide with the known ones.
