Optimal small data Scattering for the generalized derivative nonlinear Schrödinger equations

Ruobing Bai, Yifei Wu, Jun Xue

In this work, we consider the following generalized derivative nonlinear Schrödinger equation \begin{align*} i\partial_t u+\partial_{xx} u +i |u|^{2σ}\partial_x u=0, \quad (t,x)\in…
