RATH: A Maple package for finding travelling solitary wave solutions to nonlinear evolution equations. (English) Zbl 1196.35008

Summary: A Maple package RATH which outputs entirely automatically tanh-polynomial travelling solitary wave solutions of a given nonlinear evolution equation is presented. The effectiveness of RATH is demonstrated by applications to a variety of equations with physical interest as examples. Not only are previously known solutions recovered but in some cases new solutions and more general form of solutions are obtained.
