全局脉冲耦合振子布居中单团和双团态的Emergence

Emergence of one- and two-cluster states in populations of globally pulse-coupled oscillators

Leonhard Lücken, Serhiy Yanchuk

摘要:

本文的研究对象是一个相位振子系统,它们通过激发相互作用而实现全局脉冲耦合。研究了一类单峰相位响应曲线的单团簇态和双团簇态的出现和稳定性。假定PRC及其导数在加标点为零。我们发现,存在稳定的同宿连接的单集群状态的PRC的最大值位于尖峰点之前不久,共存稳定的两个集群状态时,PRC的最大值位于尖峰后不久。

英文摘要:

The subject of this paper is a system of phase-oscillators, which are globally pulse-coupled via excitatory interaction. The appearance and stability of one- and two-cluster-states is investigated for a family of unimodal phase-response-curves (PRC). The PRCs and their derivatives are assumed to be zero at the spiking point. We show that there exist stable homoclinic connections of the one-cluster state for PRCs with the maximum located shortly before the spiking point and coexisting stable two-clusters states when the maximum of the PRC is located shortly after the spike.
