title: Critical lattice size limit for synchronized chaotic state in one- and two-dimensional diffusively coupled map lattices.
abstract: We consider diffusively coupled map lattices with P neighbors (where P is arbitrary) and study the stability of the synchronized state. We show that there exists a critical lattice size beyond which the synchronized state is unstable. This generalizes earlier results for nearest neighbor coupling. We confirm the analytical results by performing numerical simulations on coupled map lattices with logistic map at each node. The above analysis is also extended to two-dimensional P -neighbor diffusively coupled map lattices.
