Error Analysis of an Implicit Spectral Scheme Applied to the Schrödinger-Benjamin-Ono System

Abstract EN

We develop error estimates of the semidiscrete and fully discrete formulations of a Fourier-Galerkin numerical scheme to approximate solutions of a coupled nonlinear Schrödinger-Benjamin-Ono system that describes the motion of two fluids with different densities under capillary-gravity waves in a deep water regime.

The accuracy of the numerical solver is checked using some exact travelling wave solutions of the system.
