摘要
本文提出了关于Sine-Gordon方程的一个守恒的九点差分格式,对解进行了先验估计,证明了数值解的收敛性和稳定性,数值实验结果表明,方法是可靠的,并且适当选择参数后,可达到很好的计算精度.
In this paper,a conserving nine points finite defference scheme for the Sine Gordon equation is proposed.The advance estimation for its solution is made,and its convergence and stability are proved.Numerical simulation of a soliton shows that the new scheme is reliable and has very good computing accuracy when the parameter is suitably selected.
