Abstract
The relationship between a driven extended system and an autonomous
spatiotemporal system is investigated in the context of coupled map
lattice models. Specifically, a locally coupled map lattice subjected
to an external drive is compared to a coupled map system with similar
local couplings plus a global interaction. It is shown that, under
some conditions, the emergent patterns in both systems are analogous.
Based on the knowledge of the dynamical responses of the driven lattice,
we present a method that allows the prediction of parameter values for
the emergence of ordered spatiotemporal patterns in a class of coupled
map systems having local coupling and general forms of global interactions.
