Experimental Realization of Periodic Deep-Water Wave Envelopes with and without Dissipation
The Korteweg–de Vries equation that describes surface gravity water wave dynamics in shallow water is well known to admit cnoidal wave solutions, i.e. periodic travelling waves with stationary wave shape. Such...

Five-wave classical scattering matrix and integrable equations
We study the five-wave classical scattering matrix for nonlinear and dispersive Hamiltonian equations with a nonlinearity of the type u∂u/∂x. Our aim is to find the most general nontrivial form of the dispersi...

Freak waves in crossing seas
We consider the modulational instability in crossing seas as a potential mechanism for the formation of freak waves. The problem is discussed in terms of a system of two coupled Nonlinear Schröedinger equatio...
