New exact solutions to the perturbed nonlinear Schrödinger’s equation with Kerr law nonlinearity

摘要

In this paper, by using the modified mapping method and the extended mapping method, we derive some new exact solutions of the perturbed nonlinear Schrödinger’s equation with Kerr law nonlinearity, which are the linear combination of two different Jacobi elliptic functions and we also consider the solutions in the limit cases.
