The partial differential equations modeling the system’s stream function and temperature are subjected to a spectral Galerkin approximation: Retrieved from ” https: A visualization of the Lorenz attractor near an intermittent cycle.

InEdward Lorenz developed a simplified mathematical model for atmospheric convection. In other projects Wikimedia Commons. These eigenvectors have several interesting implications. This point corresponds to no convection.

The Lorenz equations also arise in simplified models for lasers[4] dynamos[5] thermosyphons[6] brushless DC motors[7] electric circuits[8] chemical reactions [9] and forward osmosis. Please help improve this article by adding citations to reliable sources. Another line of the parameter space was investigated using the topological analysis.

When visualized, the plot resembled the tent mapimplying that similar analysis can be used between the map and attractor.

Initially, the two trajectories seem coincident only the yellow one can be seen, attrxttore it is drawn over the blue one but, after some time, the divergence is obvious.

Its Hausdorff dimension is estimated to be 2. As the resulting sequence approaches the central fixed point and the attractor itself, the influence of this distant fixed point and its eigenvectors will wane. A solution in the Lorenz attractor plotted at high resolution in the x-z plane. This article needs additional citations for verification.

The Lorenz equations have been the subject of hundreds of research articles, and at least one book-length study. From Wikipedia, the free encyclopedia.


In general, varying each parameter has a comparable effect by causing the system to converge toward attrattofe periodic orbit, fixed point, or escape towards infinity, however the specific ranges and behaviors induced vary substantially for each parameter. The Lorenz system is a system of ordinary differential equations first studied by Edward Lorenz. They are created by running the equations of the system, holding all but one of the variables constant and varying the last one.

The Lorenz attractor is difficult to analyze, but the action of the differential equation on the attractor is described by a fairly attratfore geometric model. An animation showing trajectories of multiple solutions in a Lorenz system.
