二阶延迟微分方程θ-方程数值解稳定性

BOUNDED STABILITY ANALYSIS OF THE θ-METHODS FOR TWO ORDER DELAY EQUATIONS

研究二阶延迟微分方程数值方法的有界稳定性,直接离散二阶延尺微分方程后,写出其相应的特征方程,考虑其方法的有界稳定性,给出了有界稳定的充要条件．

In this paper, it is investigated the Bounded Stability analysis of the θ-methods for variable coiticient and variable delay of delay differential equations, applied a variable step of θ- metheds obtains the sufficient and necessary conditions of Bounded stability for the θ- methods.
