Zusammenfassung |
We present results of numerical experiments on long-term evolution and
collisions of breathers (which correspond to envelope solitons in the NLSE
approximation) at the surface of deep ideal fluid. The collisions happen to
be nonelastic. In the numerical experiment it can be observed only after many
acts of interactions. This supports the hypothesis of "deep water
nonintegrability". The experiments were performed in the framework of the
new and refined version of the Zakharov equation free of nonessential terms
in the quartic Hamiltonian. Simplification is possible due to exact
cancellation of nonelastic four-wave interaction. |
