How Fast Elements can Affect Slow Dynamics

الأصل · EN

A chain of coupled chaotic elements with different time scales is studied. In contrast with the adiabatic approximation, we find correlations between faster and slower elements when the differences in the time scales of the elements lie within a certain range. For such correlations to occur, three features are essential: strong correlations among the elements allowing for both synchronization and desynchronization, bifurcation in the dynamics of the fastest element by the change of its control parameter, and the cascade propagation of the bifurcation. The relevance of our results to biological memory is briefly discussed.
