Dynamical origin for the occurrence of asynchronous hyperchaos and chaos via blowout bifurcations

초록

The dynamical origin for the occurrence of asynchronous hyperchaos and chaos via blowout bifurcations in coupled chaotic systems was investigated. A system of two coupled one-dimensional (1D) maps with a parameter α tuning the degree of asymmetry of coupling was considered. The type of the asynchronous intermittent attractor was determined through competition between its laminar and bursting components. The results show that an asynchronous hyperchaotic attractor appears when the strength of the bursting component is larger than that of the laminar component.
