NEW SOLITARY WAVE SOLUTIONS OF SOME NONLINEAR EVOLUTION EQUATIONS WITH DISTINCT PHYSICAL STRUCTURES

摘要

In this paper, we obtain solitary wave solutions for some nonlinear partial differential equations. The Exp-function method is used to establish solitary wave Solutions for Calogero-Bogoyavlenskii-Schiff and general modified Degasperis-Procesi and Camassa-Holm equations. The result shows that the Exp-function method yields new and more general solutions. Moreover, this method with the aid of symbolic computation provides a very effective and powerful mathematical tool for solving nonlinear evolution equations arising in mathematical physics.
