A1 - Boccaletti, Stefano A1 - Blasius, Bernd T1 - Defect-enhanced anomaly in frequency synchronization of asymmetrically coupled spatially extended systems N2 - We analytically establish and numerically show that anomalous frequency synchronization occurs in a pair of asymmetrically coupled chaotic space extended oscillators. The transition to anomalous behaviors is crucially dependent on asymmetries in the coupling configuration, while the presence of phase defects has the effect of enhancing the anomaly in frequency synchronization with respect to the case of merely time chaotic oscillators.
