solutions structure of integrable families of riccati equations and their applications to the perturbed nonlinear fractional schrodinger equation

some preliminaries about the integrable families of riccati equations and solutions structure of these equations in several cases are presented in this paper, then by using of definitions for fractional derivative we apply the new extended of tanh method to the perturbed nonlinear fractional schrodinger equation with the kerr law nonlinearity. finally by using of this method and solutions of riccati equations we obtain several analytical solutions for perturbed nonlinear fractional schrodinger equation. the proposed technique enables a straightforward derivation of parameters of solitary solutions.
