| Abstract |
We consider the effect of microscopic external noise on the collective motion of a globally coupled map in fully desynchronized states. Without the external noise a macroscopic variable shows highdimensional chaos distinguishable from random motions. With the increase of external noise intensity, the collective motion is successively simplified. The number of effective degrees of freedom in the collective motion is found to decrease as 2logs2 with the external noise variance s2. It is shown how the microscopic noise can suppress the number of degrees of freedom at a macroscopic level.
