Stability of solitary-wave solutions of coupled NLS equations with power-type nonlinearities
This paper proves existence and stability of solitary-wave solutions of a system of 2-coupled nonlinear Schrödinger equations with power-type nonlinearities arising in several models of modern physics. The existence of vector solitary-wave solutions (i.e.

Mechanical analogy for the wave‐particle: helix on a vortex filament
The small amplitude‐to‐thread ratio helical configuration of a vortex filament in the ideal fluid behaves exactly as de Broglie wave. The complex‐valued algebra of quantum mechanics finds a simple mechanical interpretation in terms of differential geometry of the space curve.

Three‐dimensional Korteweg‐de Vries equation and traveling wave solutions
The three‐dimensional power Korteweg‐de Vries equation [ut+unux+uxxx] x+uyy+uzz=0, is considered. Solitary wave solutions for any positive integer n and cnoidal wave solutions for n = 1 and n = 2 are obtained. The cnoidal wave solutions are shown to be represented as infinite sums of solitons by using Fourier series expansions and Poisson′s summation ...

Note on modulational instability of Boussinesq wavetrains
It is demonstrated that modulational instability may occur in Boussinesq wavetrains for wavenumbers k2 > 1, in contrast to the result found by Shivamoggi and Debnath. Both Whitham′s averaged Lagrangian formulation and the technique of Benjamin and Feir are used.

Analytical behavior of weakly dispersive surface and internal waves in the ocean
The (2+1)-dimensional interaction of a Riemann wave propagating along the y-axis with a long wave along the x-axis is described by the space-time fractional Calogero-Degasperis (CD) and fractional potential Kadomstev-Petviashvili (PKP) equation.

A boussinesq-type model for waves generated by flow over a bump
A uniform ow disturbed by a bump is studied. The eect of the disturbance is presented at the surface, generating wave. The wave propagation is modeled into a couple of equations, in terms of the surface elevation and the depth average velocity.
