Phys. Rev. E 68, 066203 (2003) [10 pages]Dynamical origin for the occurrence of asynchronous hyperchaos and chaos via blowout bifurcationsReceived 17 January 2003; revised 29 July 2003; published 17 December 2003 We investigate the dynamical origin for the occurrence of asynchronous hyperchaos and chaos via blowout bifurcations in coupled chaotic systems. An asynchronous hyperchaotic or chaotic attractor with a positive or negative second Lyapunov exponent appears through a blowout bifurcation. It is found that the sign of the second Lyapunov exponent of the newly born asynchronous attractor, exhibiting on-off intermittency, is determined through competition between its laminar and bursting components. When the “strength” (i.e., a weighted second Lyapunov exponent) of the bursting component is larger (smaller) than that of the laminar component, an asynchronous hyperchaotic (chaotic) attractor appears. © 2003 The American Physical Society URL:
