New exact solutions to the perturbed nonlinear Schrodinger's equation with Kerr law nonlinearity

In this paper, by using the modified mapping method and the extended mapping method, we derive some new exact solutions of the perturbed nonlinear Schrodinger'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.
