求解广义 Rosenau-Kawahara 方程的一个守恒差分格式
A conservation difference scheme for generalized Rosenau-Kaw ahara equation
摘要
Abstract
The numerical solution of the initial‐boundary value problem for generalized Rosenau‐Kawahara equation is considered , and a nonlinear two‐level finite difference scheme is designed . The difference schemes simulate two conservative quantities of the problem well . The prior estimate , existence and uniqueness of the finite difference solution are also obtained . It is show n that the finite difference scheme is second‐order convergence and unconditionally stable by discrete functional analysis method . Numerical experiments verify the theoretical results .关键词
