A new conservation difference scheme for generalized symmetrical regularized long wave equation
摘要
Abstract
The numerical solution for an initial-boundary value problem of generalized symmetrical regularized long wave equation (GSRLW) is considered. A finite difference scheme of two levels is proposed.This scheme simulates the conservation properties of the problem well. And the existence and uniqueness of the solution are also obtained. It is proved that the finite difference scheme is convergent with order 2 and stable without condition by discrete functional analysis method. The nu merical examples show this scheme is feasible.关键词
