Global existence of odd solutions for the cubic nonlinear Schrödinger equations

We consider the Schrödinger equation with the cubic nonlinear term with respect to the complex conjugate of solutions and we assume that the cubic nonlinearity has the time growth of order $\nu$. We prove that if the order $\nu$ is in the between 0 and 1/16, and the data are odd, then the small amplitude solutions are stable in the neighborhood of the free solutions.
