稀疏连接脉冲耦合振子群体的同步

Synchronization in populations of sparsely connected pulse-coupled oscillators

Alexander Rothkegel, Klaus Lehnertz

摘要:

我们提出了一个人口模型的$δ$脉冲耦合振荡器稀疏连接。该模型是作为一个演化方程的相密度,采取的形式与非局部项的偏微分方程。本文讨论了一类积分-火焰型振子的定态解的存在性、稳定性和渐近性。而对于强耦合,固定的解决方案的射击率发散和解决方案消失,小耦合允许部分同步状态出现在超临界Andronov-Hopf分岔。

英文摘要:

We propose a population model for $δ$-pulse-coupled oscillators with sparse connectivity. The model is given as an evolution equation for the phase density which take the form of a partial differential equation with a non-local term. We discuss the existence and stability of stationary solutions and exemplify our approach for integrate-and-fire-like oscillators. While for strong couplings, the firing rate of stationary solutions diverges and solutions disappear, small couplings allow for partially synchronous states which emerge at a supercritical Andronov-Hopf bifurcation.
