| 摘 要： | 讨论了带有多个滞时量的延时微分方程的数值稳定性,分析了用块θ–方法求解多延迟微分方程GPm–稳定和GPLm–稳定的条件,基于Lagrange插值,证明了块θ–方法GPm–稳定的充分必要条件是方法是A-稳定的,块θ–方法GPLm–稳定的充分必要条件是θ=1。

| Abstract: | The stability behavior of numerical solution for delay differential equations with many delays was studied. The conditions of GPmstability and GPLmstability of blockθ-method for delay differential equations with many delays were discussed. By Lagrange Interpolation, it is shown that blockθ-method is GPm-stable if and only if it is A-stable, block-θ method is GPLm-stable if and only if θ=1. |
