题 目:Quenching and reviving in systems of coupled dynamical networks
内容简介:Oscillatory behavior is essential for proper functioning of various physical and biological processes in a wide variety of natural systems,which are often composed of an ensemble of interacting oscillatory units. When the interaction occurs through a diffusive manner, the macroscopic oscillations can be suppressed by manifesting two structurally distinct oscillation quenching phenomena: amplitude death (AD) and oscillation death (OD). The phenomena of AD and OD can be responsible for a loss of dynamic activity, which may cause a large degree of degradation in the functional performance of many real-world systems. The topic of revoking AD and OD to efficiently revive rhythmicity with a general technique is of practical importance, which is an open and challenging issue in the field of nonlinear dynamics. In this talk, we will give an brief introduction on the recent study on two different collective phenomena of quenching and reviving in systems of coupled dynamical networks.
