Rhythms and turbulence in populations of chemical oscillators

Some phenomena of a statistical kind arise from populations of coupled nonlinear oscillators. In particular, we focus our attention on (A) turbulence in oscillating chemical reactions obeying deterministic kinetics, and (B) emergence and subsidence of collective rhythmicity in systems of coupled oscillators under stochastic driving forces; this phenomenon may have some relevance to physiological clocks in living organisms.
