Contractivity of Linear Multitep Methods Nonlinear Delay Differential Equations
【摘要】 修正了现有文献中关于延迟微分方程理论解稳定性结果的证明过程.此外还讨论了一类线性多步法求解该类非线性问题的数值稳定性与渐近稳定性
【Abstract】 This paper is concerned with the contractivity of the theoretical solution and numerical solutions of delay differential equations (DDES).The proofs of the existed stability results for a class of nonlinear DDES are modified.In addition,numerical stability and asymptotical stability are discussed for a class of linear multistep methods applied to this systems.
