摘要：

We characterize the complexity in dynamical systems with a random perturbation by considering the rate K of divergence of nearby orbits evolving under two different noise realizations. We discuss the meaning of K in the context of the information theory and its physical relevance for the analysis of experimental data. Our definition of complexity becomes crucial for strongly intermittent systems where K is very different from the Lyapunov exponent. This behavior is illustrated by some numerical computations. © 1994 The American Physical Society.
