Transitions induced by bounded noise

We study noise-induced transitions when the system is driven separately by a Gaussian colored noise and a non-Gaussian bounded noise with the same mean and stationary correlation. Clear differences in the nature of such transitions for these two cases are observed. These transitions are shown to be enhanced essentially by the bounded noisy driving. The results are obtained through a new approach based on numerical analysis of hyperbolic systems. (c) 2005 Elsevier B.V. All rights reserved.
