当过去的状态影响当前的动力学时,延迟质量作用系统提供了化学动力学模型。在这项工作中,我们提供了延迟稳定性的图论条件,即独立于速率常数和延迟参数的线性稳定性。特别是,当系统没有延迟时,结果适用,这意味着 ODE 系统渐近稳定。图论条件是关于网络有向物种反应图中的循环,它编码系统中不同物种如何相互作用。
Delay mass-action systems provide a model of chemical kinetics when past states influence the current dynamics. In this work, we provide a graph-theoretic condition for delay stability, i.e., linear stability independent of both rate constants and delay parameters. In particular, the result applies when the system has no delay, implying asymptotic stability for the ODE system. The graph-theoretic condition is about cycles in the directed species-reaction graph of the network, which encodes how different species in the system interact.
