We reinvestigate the intermittent synchronization phenomenon of coupled chaotic pendula that has recently been a controversy. We propose a simple numerical scheme by which one can easily determine whether the observed synchronization is a numerical artifact of computer analysis or not. By using this scheme, for certain coupling strength regime, we find that(More)
The mechanism of synchronization in the random Zaslavsky map is investigated. From the error dynamics of two particles, the structure of phase space was analyzed, and a transcritical bifurcation between a saddle and a stable fixed point was found. We have verified the structure of on-off intermittency in terms of a biased random walk. Furthermore, for the(More)
