摘要：
Under periodic boundary condition, the derivative nonlinear Schrödinger equation is studied. By virtue of Darboux transformations, I show that its level set can contain many disconnected tori of different dimensions. Such a picture was not seen before. I also give a formula for diffusions along these tori. The open problem on invariant manifolds is discussed.
