确定性反应网络的纤维分解及其应用

Fiber decomposition of deterministic reaction networks with applications

Carsten Wiuf, Chuang Xu

摘要:

确定性反应网络(RNs)是一种在粒子数量丰富的情况下对以粒子系统为特征的各种生物现象进行建模的工具。示例包括但不限于生物化学、分子生物学、遗传学、流行病学和社会科学。在本章中,我们提出了一种新的RN分解类型,称为纤维分解。使用这种分解,我们建立提升的质量行动RN保持平稳特性,包括多平稳性和绝对浓度的鲁棒性。这种提升格式简单明了,对反应网络的限制很小。我们提供的例子来说明如何提升可以用来构建RN保持某些动力学性质。

英文摘要:

Deterministic reaction networks (RNs) are tools to model diverse biological phenomena characterized by particle systems, when there are abundant number of particles. Examples include but are not limited to biochemistry, molecular biology, genetics, epidemiology, and social sciences. In this chapter we propose a new type of decomposition of RNs, called fiber decomposition. Using this decomposition, we establish lifting of mass-action RNs preserving stationary properties, including multistationarity and absolute concentration robustness. Such lifting scheme is simple and explicit which imposes little restriction on the reaction networks. We provide examples to illustrate how this lifting can be used to construct RNs preserving certain dynamical properties.
