On the Stability of Periodic Waves for the Cubic Derivative NLS and the Quintic NLS [PDF]
Journal of Nonlinear Science, 2021 We study the periodic cubic derivative non-linear Schr dinger equation (dNLS) and the (focussing) quintic non-linear Schr dinger equation (NLS). These are both $L^2$ critical dispersive models, which exhibit threshold type behavior, when posed on the line ${\mathbb R}$.
