By utilizing the logarithmic transformation and symbolic computation with ansatz functions technique, Peregrine-like rational solitons are obtained for the resonance nonlinear Schrödinger equation (R-NLSE) with Kerr law of nonlinearity. Meanwhile, the interaction between rational solitons and the kink wave is also investigated. The dynamics and many important properties of these obtained solutions are analyzed and briefly described in figures by selecting the appropriate parametric values.

With the aid of symbolic computation, an extended Jacobian elliptic function expansion method is further extended to the complex nonlinear Schrödinger + equation. As a result, 24 families of the envelope doubly-periodic solutions with Jacobian elliptic functions are obtained. When the modulus m → 1 or zero, the corresponding six envelope solitary wave solutions and six envelope singly-periodic (trigonometric function) solutions are also found. This powerful method can also be applied to other equations, such as the nonlinear Schrödinger equation and Zakharov equation.

Kerr Law Nonlinearity

In this paper, using the methods of ansatz, sine-cosine and He’s semi-inverse variation, non-topological 1-soliton solution to Resonant Nonlinear Schrodinger Equation with Kerr law nonlinearity is obtained. The results show that these methods are very effective ones for finding exact solutions to various types of nonlinear evolution equations appearing in the studies of science and engineering.
