摘要
本文提出中层点数为六点的一类三层显式格式,其截断误差为O(τh+h^2),最佳稳定性条件为|R|≤4.67377。
In this paper,we establish a class of three-level explicit difference schemes with a parameter for the dispersive equation ut-auxxx. The truncate errors of the schemes are O(τA + h2). By means of mathematical analysis,the optimal parameter in the schemes for the highest stability has been obtained and the best conditions for the stability are -0.3631≤R≤4.
