On the integrability of Degasperis-Procesi equation: control of the Sobolev norms and Birkhoff resonances

Roberto Feola, Filippo Giuliani, Stefano Pasquali

We consider the dispersive Degasperis-Procesi equation $u_{t} - u_{xx t} - c u_{xxx} + 4 c u_{x} - u u_{xxx} - 3 u_{x} u_{xx} + 4 u u_{x} = 0$ with $c \neq = 0$ . In \cite{Deg} t…
