Abstract:
We have found a variety of oscillating patterns in the Belousov-Zhabotinsky (BZ) reaction-diffusion system with global negative
feedback. Bulk oscillations and wave patterns arise at low values of the feedback strength. When the feedback exceeds a critical
value, cluster patterns arise. Besides the standing, irregular, and localized clusters observed earlier, we have found new types of
clusters: three-phase, localized irregular, and localized oscillatory clusters. A model of three identical Oregonators with global
negative coupling yields the same bifurcation scenario as found in our experiments.
