On-off intermittency in random map lattices

Abstract

In this paper we study numerically an ensemble of random driving logistic maps. There are two accessible cases of on-off intermittency in the system for different values of parameters. The first one corresponds to the loss of stability of the fixed point, while the second one is due to the instability of the synchronous motion of the ensemble. It shows that the two cases of intermittency belong to the same class of universality.
