Abstract

Propagation velocities of disturbances are analyzed in chaotic spatially extended systems with local and long-range couplings. For nearestneighbours interactions two distinct speed selection mechanisms for propagating fronts are found. One mechanism can be interpreted within a linearstability analysis, while the origin of the second one is fully non-linear. For long-range couplings, decaying as powers of the distance, the spreading-rate of disturbances increase exponentially in time.
