The -expansion method and its applications to two nonlinear Schrodinger equations describing the propagation of femtosecond pulses in nonlinear optical fibers

The propagation of the optical solitons is usually governed by the nonlinear Schrodinger equations. In this article, the two variable -expansion method is employed to construct exact traveling wave solutions with parameters of two higher order nonlinear Schrodinger equations. When the parameters are...

Summary:The propagation of the optical solitons is usually governed by the nonlinear Schrodinger equations. In this article, the two variable -expansion method is employed to construct exact traveling wave solutions with parameters of two higher order nonlinear Schrodinger equations. When the parameters are replaced by special values, the well-known solitary wave solutions of these equations rediscovered from the traveling waves. This method can be thought of as the generalization of well-known original -expansion method proposed by Wang et al. It is shown that the two variable -expansion method provides a more powerful mathematical tool for solving many other nonlinear PDEs in mathematical physics.
