Proof We start the proof with a lemma which
Let (u,v,P,η)(u,v,P,η)be an x-periodic solution to the irrotational water wave problem (1), (2), (3), (4), (5) and (6), with the property that JIB-04 η and the horizontal component u at the surface are both symmetric about x=c(t)x=c(t)at any instant of time. Then the solution defines a traveling wave.

The Ginzburg–Landau equation  and  is one of the most-studied nonlinear equations in physics. It describes a vast variety of phenomena from nonlinear waves to second-order phase transitions, from superconductivity, superfluidity, and Bose–Einstein condensation to liquid crystals and strings in field theory. The Ginzburg–Landau equation with fractional derivatives was suggested in  and studied in  and , where precipitation is used to describe processes in media with fractal dispersion or long-range interaction.
