While the equations look simple enough they lead to wondrous trajectories, some examples of which are illustrated below.

The definition of an attractor uses a metric on the phase space, but the resulting notion usually depends only on the topology of the phase space. In other projects Wikimedia Commons.

Interactive Lorenz Attractor

Many other definitions of attractor occur in the literature. If a strange attractor is chaotic, exhibiting sensitive dependence on initial conditionsthen any two arbitrarily close alternative initial points on the attractor, after any of various numbers of iterations, will lead to points that are arbitrarily far apart subject to the confines of the attractorand after any of various other numbers of iterations will lead to points that are arbitrarily close together.

The partial differential equations modeling the system’s stream function and temperature are subjected to a spectral Galerkin approximation: A time series corresponding to this attractor is a quasiperiodic series: Based on your location, we recommend that you select: The three axes are each mapped to a different instrument.


The series does not form limit cycles nor does it ever reach a dde state.

This colors on this graph represent the frequency of state-switching for each set of parameters r,b. Random attractors and time-dependent invariant measures”. Two simple attractors are a fixed point and the ztractor cycle.

March Learn how and when to remove this template message. Atrator About Live Editor. For example, in physics, one frequency may dictate the rate at which a planet orbits a star while a second frequency describes the oscillations in the distance between the two bodies.

This problem was the first one to be resolved, by Warwick Tucker in Similar features apply to linear differential equations. A trajectory of the dynamical system in the attractor does not have to satisfy any special constraints except for remaining on the attractor, forward in time.

The lorenz attractor was first studied by Ed N. Views Read Edit View history.

From Wikipedia, the free encyclopedia. The Lorenz oscillator is a 3-dimensional dynamical system that exhibits chaotic flow, noted for its lemniscate shape.

Aristotle believed that objects moved only as long as d were pushed, which is an early formulation of a dissipative attractor. It also arises naturally in models of lasers and dynamos.

It is notable for having chaotic solutions for certain parameter values and initial conditions. Notice the two “wings” of the butterfly; these correspond to two different sets of physical behavior of the system.

The trajectory may be periodic or chaotic. For example, some authors require that an attractor have positive measure preventing a point from being an attractoratrator relax the requirement that B A be a neighborhood. The Lorenz attractor was first described in by the meteorologist Edward Lorenz.

An animation showing the divergence of nearby solutions to the Lorenz system.

This is what the standard Lorenz butterfly looks like: The Lorenz equations have been the subject of hundreds of research articles, and at least one book-length study. The fluid is atractoe to circulate in two dimensions vertical and horizontal with periodic rectangular boundary conditions.
