چکیده

Abstract General rogue waves in (1+1)-dimensional three-wave resonant interaction systems are derived by the bilinear method. These solutions divided into three families, which correspond to a simple root, two roots and double root of certain quartic equation arising from dimension reduction, respectively. It is shown that while first family associated with exists for all signs nonlinear coefficients equations, other families can only exist so-called soliton-exchange case, where have signs. Many these wave solutions, such as those roots, ones generated $2\times 2$ block determinant double-root higher-order new not been reported before. Technically, our derivation case achieved generalization previous reduction procedure method, this generalized allows us treat arbitrary multiplicities. Dynamics also examined, patterns presented. Connection between earlier Darboux transformation explained.

Rogue waves emerging from the resonant interaction of three waves.

We introduce a novel family of analytic solutions of the three-wave resonant interaction equations for the purpose of modeling unique events, i.e., "amplitude peaks" which are isolated in space and time. The description of these solutions is likely to be a crucial step in the understanding and forecasting of rogue waves in a variety of multicomponent wave dynamics, from oceanography to optics a...

Evolution of Rogue Waves in Interacting Wave Systems

Large amplitude water waves on deep water has long been known in the sea faring community, and the cause of great concern for, e.g., oil platform constructions. The concept of such freak waves is nowadays, thanks to satellite and radar measurements, well established within the scientific community. There are a number of important models and approaches for the theoretical description of such wav...

The Three-Wave Resonant Interaction Equations: Spectral and Numerical Methods

The spectral theory of the integrable partial differential equations which model the resonant interaction of three waves is considered with the purpose of numerically solving the direct spectral problem for both vanishing and non vanishing boundary values. Methods of computing both the continuum spectrum data and the discrete spectrum eigenvalues are given together with examples of such computa...

Rogue Waves in Spatially Extended Optical Systems

Giant anomalous events may occur in systems characterized by many waves, with extremely high amplitude waves appearing with a probability much higher than expected for a random dynamics. Such rare, and giant, events are known to occur on the ocean surface and have been named, in that context, “rogue waves”. We present here some recent experimental results on the statistical properties of giant ...
