Abstract(in Japanese) (See Japanese page)
Abstract(in English) The maps or flows globally coupled via their mean field have various interesting phases under the balance between the randomness in each element and the coherence due to the coupling.Some new findings are presented including the phase-synchronization phenomenon in the coupled flows and a mechanism which realizes the posi-nega switch in the globally coupled maps.It is also shown that even in the turbulent phase the global quasi-periodic motion of the maps is in action.I present a new extended coupled map model with inverse power law interaction which shares all the salient characteristics of the globally coupled model.To date coupled maps and coupled flows have been two different subjects of research.The basic motiftrough this talk is a new recognition that the universality idea can be transferred to the synchronizing maps and flows.
