Self-organized criticality. (English) Zbl 1230.37103
Summary: We show that certain extended dissipative dynamical systems naturally evolve into a critical state, with no characteristic time or length scales. The temporal ‘fingerprint’ of the self-organized critical state is the presence of flicker noise or \(1/f\) noise; its spatial signature is the emergence of scale-invariant (fractal) structure.
