摘要
本文将研究多延迟微分方程数值解的稳定性 ,我们考虑如下线性试验方程 U′( t) =AU( t) + ∑mj=1Bj U( t- τj)二种 θ——方法的数值特征 ,其中 A,B1,… ,Bm为复矩阵 ,给出了二种θ—方法是 GPm
This paper deals with the stability of numerical solution for differential-equations with several delays. By the two kinds of θ -method, we consider the following linear test equation U′(t)=AU(t)+∑mj=1B jU(t-τ j), where A,B 1,...,B m are complex matrixes. A sufficient and necessary condition for the GP m stability is given.
