Statistical scaling laws for chemical oscillators

Universality classes are defined for the nonlinear, oscillatory Belousov-Zhabotinsky (BZ) reaction. We examine the decay to asymptotic steady state for supercritical Hopf bifurcation by considering a phenomenological approach supported by numerical simulations and confirmed by a analytical description. The formalism is general and it is expected to be universal for systems exhibiting Hopf bifurcations.
