报告摘要:In this talk we study the long wave asymptotic behavior of the rotation-Green-Naghdi equations, which could be used to describe the propagation of  long-crested shallow-water waves  in the equatorial ocean regions with the Coriolis effect due to Earth's rotation.  We demonstrate the lift span of the solution to the R-GN model equations in a Sobolev space by the refined energy estimates. Then we provide a rigorous justification from the solutions of the R-GN equations to the associated solution of the right-left R-BBM or KdV equation in the KdV regime with the small amplitude and the large wavelength. This is the first result on the issue that the solution of the R-GN equations is well approximated by the two directional R-BBM in the general regular initial data setting.
