Global well-posedness for the higher order non-linear Schrödinger equation on modulations spaces

X. Carvajal, P. Gamboa, R. Santos

We consider the initial value problem (IVP) associated to a higher order nonlinear Schrödinger (h-NLS) equation $ \partial_{t}u+ia \partial^{2}_{x}u+ b\partial^{3}_{x}u+ic_1|u|^{2…
