Modulational instabilities of perturbed nonlinear Schroedinger-type equations
In this thesis we examine the stability thresholds for nonlinear Schrödinger-type equations. We use variational techniques to rederive the modulational instability criterion in the case with cubic nonlinearity, considering the equation as a finite dimensional dynamical system. We proceed to the anal...
