On the construction of almost periodic solutions for the derivative nonlinear Schrödinger equation

Yuchen WU, Xiaoping Yuan

In this paper, we consider a derivative nonlinear Schrödinger equation $$\mathrm{i}{\partial }_{t}u+{\partial }_{xx}u-V\ast u+\mathrm{i}|u{|}^2{\partial }_{x}u=0$$ on the torus…
