小反应网络的非退化多平稳性

Nondegenerate multistationarity in small reaction networks

Anne Shiu, Timo de Wolff

摘要:

近年来,许多注意力集中在以下代数问题所产生的应用:哪些化学反应网络,当采取与质量作用动力学,承认多个积极的稳定状态?这个问题背后的兴趣是稳定的稳态。作为迈向这个难题的一步,在这里我们解决多个非简并正稳态的问题。在数学上,这是问是否某些家庭的参数化,真正的,稀疏的多项式系统曾经承认多个正实根是简单的。我们的主要结果解决了某些类型的小型网络的这个问题,我们的技术为大型网络指明了前进的方向。

英文摘要:

Much attention has been focused in recent years on the following algebraic problem arising from applications: which chemical reaction networks, when taken with mass-action kinetics, admit multiple positive steady states? The interest behind this question is in steady states that are stable. As a step toward this difficult question, here we address the question of multiple nondegenerate positive steady states. Mathematically, this asks whether certain families of parametrized, real, sparse polynomial systems ever admit multiple positive real roots that are simple. Our main results settle this problem for certain types of small networks, and our techniques point the way forward for larger networks.
