摘要: 通过分析线性化系统的特征值并利用分歧定理,研究了一类具有自动催化作用和饱和定律的双分子模型的图灵不稳定性和霍普夫分歧,并利用数值模拟的方法证明和解释了理论结果.

关键词: 双分子模型, 自动催化作用, 图灵不稳定性, 霍普夫分歧

Abstract: This paper deals with a bimolecular model with autocatalysis and saturation law. By analyzing the eigenvalues of the linearized system and using the bifurcation theory, we derive the conditions to occurrence Turing instability and Hopf bifurcation from the unique constant solution. Numerical simulations are presented to verify and illustrate the theoretical results.

Key words: Bimolecular model, Autocatalysis, Turing instability, Hopf bifurcation
