Conservative compact finite difference scheme for the coupled Schrödinger–Boussinesq equation

In this article, two conserved compact finite difference schemes for solving the nonlinear coupled Schrodinger–Boussinesq equation are proposed. The conservative property, existence, convergence, and stability of the difference solutions are theoretically analyzed. The numerical results are reported to demonstrate the accuracy and efficiency of the methods and to confirm our theoretical analysis. © 2016Wiley Periodicals, Inc.
