论文摘要
图灵的模式形成理论是解释自然界观察到的各种时空结构的最流行理论手段之一,因此,在许多不同的领域中找到了应用。尽管图灵模式已经在连续支持和网络上进行了彻底研究,但在具有高阶相互作用的系统中,仅尝试了一些尝试。在本文中,我们提出了一种在反应扩散系统中包括组相互作用的方法,并研究了它们对图灵模式形成的影响。为了实现这一目标,我们重写了最初通过图灵以通用形式研究的问题,该形式以超图的形式解释了任何顺序的相互作用描述,并且我们证明,不同交互作用的相互作用可能会增强或抑制Turing模式的出现。我们的结果阐明了具有多体相互作用的系统中模式形成的机制,并为图灵原始框架的进一步扩展铺平了道路。
Turing theory of pattern formation is among the most popular theoretical means to account for the variety of spatio-temporal structures observed in Nature and, for this reason, finds applications in many different fields. While Turing patterns have been thoroughly investigated on continuous support and on networks, only a few attempts have been made towards their characterization in systems with higher-order interactions. In this paper, we propose a way to include group interactions in reaction-diffusion systems, and we study their effects on the formation of Turing patterns. To achieve this goal, we rewrite the problem originally studied by Turing in a general form that accounts for a microscropic description of interactions of any order in the form of a hypergraph, and we prove that the interplay between the different orders of interaction may either enhance or repress the emergence of Turing patterns. Our results shed light on the mechanisms of pattern-formation in systems with many-body interactions and pave the way for further extensions of Turing original framework.
