时变网络上的Turing模式理论

The theory of Turing patterns on time varying networks

Julien Petit, Ben Lauwens, Duccio Fanelli, Timoteo Carletti

摘要:

研究了锚定在时变网络上的多种群模型的斑图形成过程。一个非齐次扰动叠加到一个齐次稳定的不动点上,可以放大一个新的不稳定机制,让人想起图灵类型,由网络动力学引起。通过适当地调整施加的网络演化的频率,可以使所检查的系统在有限的时间窗口内表现为其平均对应物。这是关键的观察,以获得一个封闭的分析预测的发病的不稳定性的时间依赖的框架。连续和分段恒定的周期时变网络将进行分析,为所提出的方法奠定基础。还将讨论非周期性设置的扩展。

英文摘要:

The process of pattern formation for a multi-species model anchored on a time varying network is studied. A non homogeneous perturbation superposed to an homogeneous stable fixed point can amplify, as follows a novel mechanism of instability, reminiscent of the Turing type, instigated by the network dynamics. By properly tuning the frequency of the imposed network evolution, one can make the examined system behave as its averaged counterpart, over a finite time window. This is the key observation to derive a closed analytical prediction for the onset of the instability in the time dependent framework. Continuously and piecewise constant periodic time varying networks will be analysed, to set the ground for the proposed approach. The extension to non periodic settings will also be discussed.
