Smale's horseshoe
WebbHyperbolic horseshoes with alternating orientation, called half-orientable horseshoes, are proved to represent the nonwandering set of the maps in certain parameter regions. We … WebbIn the early 1960s, the young American mathematician Steve Smale(1930-...) was working on the beach of Copacabana when he made a discovery ...He discovered a horseshoe! Not a real one, but a mathematical object : a transformation combining a scaling and a contraction, but also a folding. It transforms a square into the shape of a horseshoe.

Did you know?
In the mathematics of chaos theory, a horseshoe map is any member of a class of chaotic maps of the square into itself. It is a core example in the study of dynamical systems. The map was introduced by Stephen Smale while studying the behavior of the orbits of the van der Pol oscillator. The action of the map is … Visa mer The horseshoe map f is a diffeomorphism defined from a region S of the plane into itself. The region S is a square capped by two semi-disks.
