双曲型多重套网格有限差分方程简便稳定性判别法

The Multiple Nesting Grid Difference Methods for Hyperbolic Systems and Its Convenient Stable Criterion

讨论了双曲型偏微分方程式多重套网格有限差分方法的稳定性,并讨论多重套网格差分逼近MND的耦合稳定判别条件的简便形式,得到了一系列简便的判别稳定性的引理及定理。

In this paper the multiple nesting grid difference methods for hyperbolic initial multiple boundaries value problems are presented, and a series of convenient stable criterions are obtained.
