|Title:||Ill-posedness for the derivative Schrodinger and generalized Benjamin-Ono equations|
|Abstract:||Ill-posedness is established for the initial value problem (IVP) associated to the derivative nonlinear Schrodinger equation for data in H-s (R), s < 1/2. This result implies that best result concerning local well-posedness for the IVP is in H-s ( R), s <greater than or equal to> 1/2. It is also shown that the (IVP) associated to the generalized Benjamin-Ono equation for data below the scaling is in fact ill-posed.|
