Md. Vieira et Aj. Lichtenberg, NONUNIVERSALITY OF WEAK SYNCHRONIZATION IN CHAOTIC SYSTEMS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 56(4), 1997, pp. 3741-3744
We show that the separate properties of weak synchronization (WS) and
strong synchronization (SS), reported recently by Pyragas [Phys. Rev.
E 54, R4508 (1996)], in unidirectionally coupled chaotic systems, are
not generally distinct properties of such systems. In particular, we f
ind analytically for the tent map and numerically for some parameters
of the circle map that the transitions to WS and SS coincide.
