Multiple soliton solutions for the Nagumo equation and the modified general Burgers-Fisher equation. (English) Zbl 1198.35204

Summary: A generalized tanh-function method is used for constructing exact travelling wave solutions for Nagumo’s equation and the modified generalized Burger-Fisher equation. Also new multiple soliton solutions are obtained for both equations. Limit case of the time delay is studied and the results of the general Burgers-Fisher equations are verified.
