64 results about "Standard map" patented technology

The standard map (also known as the Chirikov–Taylor map or as the Chirikov standard map) is an area-preserving chaotic map from a square with side 2π onto itself. It is constructed by a Poincaré's surface of section of the kicked rotator, and is defined by: pₙ₊₁=pₙ+Ksin(θₙ) θₙ₊₁=θₙ+pₙ₊₁ where pₙ and θₙ are taken modulo 2π. The properties of chaos of the standard map were established by Boris Chirikov in 1969.
