Abstract
We study phase synchronization in a chain of weakly coupled chaotic os cillators. In the synchronous state, the phases of oscillators are loc ked, while the amplitudes remain chaotic. We demonstrate that the coex istence of several clusters of mutually synchronized elements and glob al synchronization of all oscillators is possible. Two mechanisms of t he transition to global synchronization are shown. The dynamics of spa tiotemporal defects is discussed for the cases of phase-coherent and f unnel Rossler oscillators.
