摘要：

We study the nonequilibrium phenomena in globally coupled active rotators with multiplicative and additive noises, It is shown that at a critical value of the multiplicative noise intensity the system undergoes noise-induced transition from a one-cluster state to a two-cluster state, Additive noise suppresses the effect of the multiplicative noise on the system, increasing the critical value of the multiplicative noise intensity, The system shows a reentrant transition at intermediate additive noise intensity.
