Abstract
We investigate the behavior of the residence times density function for dif ferent nonlinear dynamical systems with limit cycle behavior and perturbed parametrically with a colored noise. We present evidence that, underlying t he stochastic resonancelike behavior with the noise correlation time, there is an effect of optimal localization of the system trajectories in the pha se space. This phenomenon is observed in systems with different nonlinearit ies, suggesting a degree of universality. [S0031-9007(99)08901-8].
