Résumé :

A method is presented which permits to calculate the stationary probability density of non equilibrium systems subjected to wide band external colored noise. It consists of a systematic perturbation expansion in terms of the correlation time of the noise. The method is presented in detail for noise of the Ornstein-Uhlenbeck type. It is used to illustrate the effect of correlations on two examples of noise induced transitions.
