A Three-Levels Finite Difference Method for Nonlinear Regularized Long-Wave Equation

abstract:
In this paper, a finite difference method is presented for the initial boundary-value problem for nonlinear Regularized Long-Wave Equation. An energy conservative finite difference scheme of three-levels is proposed. On the basis of an inequality about norms, convergence and stability of the difference solution is proved. The rate of convergence of the difference solution is $O(h^{2}+\tau^{2})$. The numerical results are presented.
