反应系统时滞稳定性的一个图论条件

A graph-theoretic condition for delay stability of reaction systems

Gheorghe Craciun, Maya Mincheva, Casian Pantea, Polly Y. Yu

摘要:

延迟质量作用系统提供了一个化学动力学模型,当过去的状态影响当前的动态。在这项工作中,我们提供了一个图论条件的延迟稳定性,即,线性稳定性与速率常数和延迟参数无关。特别地,当系统没有时滞时,该结果也适用,这意味着常微分方程系统是渐近稳定性。图论条件是关于网络的有向物种反应图中的循环,它编码了系统中不同物种如何相互作用。

英文摘要:

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.
