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。
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.
