teoría del caos
Scope note: Estudio de sistemas que responden desproporcionadamente (no linealmente) a las condiciones iniciales o estímulos perturbadores. Los sistemas no lineales pueden manifestar "caos", que se caracteriza clásicamente como una dependencia sensible a las condiciones iniciales. Los sistemas caóticos, aunque se distinguen de los sistemas periódicos más ordenados, no son aleatorios. Cuando se muestra apropiadamente su comportamiento en el tiempo (en "fase espacio"), son evidentes restricciones que se describen como atractores extraños. Las representaciones en fase espacio de sistemas caóticos o atractores extraños, generalmente muestran auto semejanza fractal (FRACTALES) a través de las escalas temporales. Los sistemas naturales, incluyendo los biológicos, frecuentemente muestran dinámica no lineal y caos.

Scope note: The study of systems which respond disproportionately (nonlinearly) to initial conditions or perturbing stimuli. Nonlinear systems may exhibit "chaos" which is classically characterized as sensitive dependence on initial conditions. Chaotic systems, while distinguished from more ordered periodic systems, are not random. When their behavior over time is appropriately displayed (in "phase space"), constraints are evident which are described by "strange attractors". Phase space representations of chaotic systems, or strange attractors, usually reveal fractal (FRACTALS) self-similarity across time scales. Natural, including biological, systems often display nonlinear dynamics and chaos.
