On the Periodic Cauchy problem for a coupled system of third-order nonlinear Schrödinger equations

Marcia Scialom, Luciana Bragança

We investigate some well-posedness issues for the initial value problem (IVP) associated to the system \begin{equation} \{ \begin{array} [c]{l} 2i\partial_{t}u+q\partial_{x}^{2}u+i…
