U. Parlitz et al., SUBHARMONIC ENTRAINMENT OF UNSTABLE PERIOD ORBITS AND GENERALIZED SYNCHRONIZATION, Physical review letters, 79(17), 1997, pp. 3158-3161
Chaos synchronization of nonidentical unidirectionally coupled systems
is investigated and characterized in terms of the entrainment ratios
of unstable periodic orbits. The implications of subharmonic entrainme
nt for generalized synchronization are discussed and illustrated for d
iscrete and continuous systems. [S0031-9007(97)04380-9].
