<mathematics> (After Edward Lorenz, its discoverer) A region in the phase space of the solution to certain systems of (non-linear) differential equations. Under certain conditions, the motion of a particle described by such as system will neither converge to a steady state nor diverge to infinity, but will stay in a bounded but chaotically defined region. By chaotic, we mean that the particle's location, while definitely in the attractor, might as well be randomly placed there. That is, the particle appears to move randomly, and yet obeys a deeper order, since is never leaves the attractor. Lorenz modelled the location of a particle moving subject to atmospheric forces and obtained a certain system of {ordinary differential equations}. When he solved the system numerically, he found that his particle moved wildly and apparently randomly. After a while, though, he found that while the momentary behaviour of the particle was chaotic, the general pattern of an attractor appeared. In his case, the pattern was the butterfly shaped attractor now known as the Lorenz attractor. (1996-01-13)

The Lorenz system is a system of ordinary differential equations first studied by mathematician and meteorologist Edward Lorenz. It is notable for having chaotic solutions for certain parameter values and initial conditions.

Lorenz Leonard Lindelöf (13 November 1827, Karvia, Finland – 3 March 1908, Helsinki) was a Finnish mathematician and astronomer.

Lorenz Nikolai Achté (25 May 1835 – April 18, 1900) was a Finnish opera singer, composer, conductor and music teacher. He was born in Pori, and was one of the Finnish Opera's first artists, together with his wife Emmy Achté.

František Vladimír Lorenc (24 December 1872 – 24 May 1957), known in Portuguese as Francisco Valdomiro Lorenz, was a Czech-born polyglot and philosopher born in Zbyslav (nowadays part of the Czech Republic). He was one of the first Esperantists in the world, and was able to communicate in over 100 different languages.

In the mathematical field of dynamical systems, an attractor is a set of states toward which a system tends to evolve, for a wide variety of starting conditions of the system. System values that get close enough to the attractor values remain close even if slightly disturbed.
