**Random dynamical system** — In mathematics, a random dynamical system is a measure theoretic formulation of a dynamical system with an element of randomness , such as the dynamics of solutions to a stochastic differential equation. It consists of a base flow, the noise ,… … Wikipedia

**Base flow (random dynamical systems)** — In mathematics, the base flow of a random dynamical system is the dynamical system defined on the noise probability space that describes how to fast forward or rewind the noise when one wishes to change the time at which one starts the random… … Wikipedia

**Pink noise** — This article is about the signal in information theory. For the band, see PINKNOISE. Colors of noise White Pink Red (Brownian) Grey Pink noise or 1/ƒ noise (sometimes also called flicker noise) is a signal or process with a frequency spectrum… … Wikipedia

**Absorbing set (random dynamical systems)** — In mathematics, an absorbing set for a random dynamical system is a subset of the phase space that eventually contains the image of any bounded set under the cocycle ( flow ) of the random dynamical system. As with many concepts related to random … Wikipedia

**Chaos theory** — This article is about chaos theory in Mathematics. For other uses of Chaos theory, see Chaos Theory (disambiguation). For other uses of Chaos, see Chaos (disambiguation). A plot of the Lorenz attractor for values r = 28, σ = 10, b = 8/3 … Wikipedia

**Pullback attractor** — In mathematics, the attractor of a random dynamical system may be loosely thought of as a set to which the system evolves after a long enough time. The basic idea is the same as for a deterministic dynamical system, but requires careful treatment … Wikipedia

**Recurrence quantification analysis** — (RQA) is a method of nonlinear data analysis (cf. chaos theory) for the investigation of dynamical systems. It quantifies the number and duration of recurrences of a dynamical system presented by its phase space trajectory.BackgroundThe… … Wikipedia

**Neural oscillation** — is rhythmic or repetitive neural activity in the central nervous system. Neural tissue can generate oscillatory activity in many ways, driven either by mechanisms localized within individual neurons or by interactions between neurons. In… … Wikipedia
