释义
chaos theory

Geography
  • ‘Chaos Theory deals with simple, deterministic, non-linear, dynamic, closed systems…[that] are extremely sensitive to initial conditions, resulting in an unpredictable chaotic response to any minute initial difference or perturbation’ (Reitsma (2003) Geoforum 34, 1). Chaotic behaviour is not random—current conditions are still linked to future conditions—and chaotic systems do not repeat themselves exactly, but may behave in a loosely recurrent fashion. See Phillips (2003) PPG 27, 1.


Economics
  • A theory that describes the behaviour of deterministic nonlinear dynamic systems characterized by sensitivity to initial conditions. Sensitivity means that small differences in starting positions for the system result in large differences in the positions of the system achieved after a finite length of time. Chaos makes long-term forecasting impossible: even the smallest error in determining initial conditions will lead to a large divergence of forecast from actual outcome.
