We show that the limit infimum, as time $\,t\,$ goes to infinity, of any uniformly bounded in time $H^{3/2+}\cap L^1$ solution to the Intermediate Long Wave equation converge to zero locally in an increasing-in-time region of space of order $\,t/\log(t)$. Also, for solutions with a mild $L^1$-norm growth in time is established that its limit infimum converge to zero, as time goes to infinity. This confirms the non existence of breathers and other solutions for the ILW model moving with a speed… Expand

We are interested in the long time asymptotic behavoir of solutions to the scalar Zakharov system \[ i u_{t} + \Delta u = nu,\] \[n_{tt} - \Delta n= \Delta |u|^2\] and the Klein-Gordon ZakharovExpand

On Long Time Behavior of Solutions of the Schrödinger-Korteweg-de Vries System
TLDR
It is shown that solutions of the Schrodinger-Korteweg-de Vries system decay to zero in the energy space, independent of the integrability of the equations involved and it does not require any size assumptions. Expand
