Problems of complex behavior of random dynamical systems is investigated based on numerically observed noise-induced phenomena in Belousov-Zhabotinsky map (BZ map) and modified Lasota-Mackey map with presence of noise.
We found that (i) both noise-induced chaos and noise-induced order robustly coexist, and that (ii) asymptotical periodicity of density is varied according to noise amplitude.
Applications to time series analysis is also discussed.
