比例延迟微分方程二阶导数方法的稳定性(英文)
The stability of the second derivative method for the pantograph equation
【摘要】 讨论了比例延时微分方程的二阶导数方法。为了解决研究长时间解性态时遇到的存储问题,变步长格式被采纳,给出了解比例延时微分方程的二阶导数方法稳定性的充分条件。
【Abstract】 The so-called second derivative method for pantograph equation is discussed.In order to solve the storage problem involved in studying the long time behavior of the solution,a grid with variable stepsize is adopted.A sufficient condition for the stability of the second derivative method for the pantograph equation is shown.
