摘要：

The periodic initial boundary value problem of the coupled Schrodinger-Boussinesq equations is studied by the time-splitting Fourier spectral method. A time-splitting spectral discretization for the Schrodinger-like equation is applied, while a Crank-Nicolson/leap-frog type discretization is utilized for time derivatives in the Boussinesq-like equation. Numerical tests show that the time-splitting Fourier spectral method provides high accuracy for the coupled Schrodinger-Boussinesq equations. (C) 2011 Elsevier B.V. All rights reserved.
