主 题:New sub-equation method (G/G,1/G)-expansion method Generalized Riccati equation mapping method Perturbed nonlinear Schrödinger equation Exact solutions.
摘 要:In a previous work,Zayed and Al-Nowehy have applied the Riccati equation mapping method combined with the generalized extended(G/G)-expansion method and found new exact solutions of the nonlinear KPP *** the present article,we propose a different method,namely,a new sub-equation method consists of the Riccati equation mapping method and the(G/G,1/G)-expansion method to find new exact solutions of the perturbed nonlinear Schrödinger equation with Kerr law nonlinearity in optical fiber *** proposed method is not found ***,trigonometric and rational function solutions are *** solutions of the generalized Riccati equation are presented for the first time which are not reported *** solutions of the given nonlinear equation can be applied in ocean engineering for calculating the height of tides in the ocean.
