Application of Exp-function method for a system of three component-Schroedinger equations

An algorithm is devised for deriving exact traveling wave solutions of a three-component system of nonlinear Schroedinger (NLS) equations by means of Exp-function method. This method was previously applied to nonlinear partial differential equations (NLPDEs) or two coupled NLPDEs, here it is applied to three coupled NLPDES. This work continues to reinforce the idea that the Exp-function method, with the help of symbolic computation, provides a powerful mathematical tool for solving nonlinear partial differential equations.
