化学反应网络的分段线性模型

Piecewise linear models of chemical reaction networks

Ajit Kumar, Krešimir Josić

摘要:

我们表明,某些非线性动力系统的非线性形式的希尔函数,可以近似分段线性动力系统。由此产生的分段系统具有封闭形式的解决方案,可以用来理解的行为的完全非线性系统。我们证明减少使用几何奇异摄动理论,并说明在网络建模的遗传开关和遗传振荡器的结果。

英文摘要:

We show that certain non-linear dynamical systems with non-linearities in the form of Hill functions, can be approximated by piecewise linear dynamical systems. The resulting piecewise systems have closed form solutions that can be used to understand the behavior of the fully nonlinear system. We justify the reduction using geometric singular perturbation theory, and illustrate the results in networks modeling a genetic switch and a genetic oscillator.
