摘要
Abstract
In this paper, a finite different method for an initial-boundary value problem of generalized symmetric regularized long wave equation is considered. An average implicit and energy conservative fi nite difference scheme with the weighted coefficient d is proposed. Existense and uniqueness of the nu merical solutions are shown. The second-order convergence and the stability of the numerical solutions are proved by the discrete functional analysis. Numerical experiments show that this method is efficient and making appropriate adjustments to the weighted coefficient 0 would make calculations with higher precision.关键词
