Abstract
Oceans crossing the Solar System attract people’s attention: the Earth, Enceladus, and Titan. On a variable-coefficient nonlinear dispersive-wave system for the shallow oceanic environment, our symbolic computation yields two non-auto-Bäcklund transformations and auto-Bäcklund transformations with some solitons, with regard to the wave elevation and surface velocity of the water wave, which depend on the variable coefficients. This paper could be of some use for the future oceanic studies in the Solar System.
Notes
1.Examples are the investigations on the interaction of linear modulated waves and unsteady dispersive hydrodynamic states with the applications to the shallow water waves [17], water-wave scattering by multiple thin vertical barriers [16], water-wave scattering by three thin vertical barriers [18], internal tides over a shallow ridge with a high-resolution downscaling regional ocean model [19], shallow overturning circulation in the Indian Ocean [20] and propagation of long-crested water waves [21].
Two branches appear because of the choices based on the “±” signs.
