Abstract
We consider the equation \begin{equation*} \px(\pt u+\px f(u)-\beta \pxxx u)=\gamma u, \end{equation*} that includes the short pulse, the Ostrovsky-Hunter, and the Korteweg-deVries ones. We consider here the asymptotic behavior as $\gamma\to 0$. The proof relies on deriving suitable a priori estimates together with an application of the compensated compactness method in the $L^p$ setting.File in questo prodotto:
