Arnold's Cat Map

Dynamical Systems and Differential Equations

Arnold's cat map is a chaotic transformation of the torus into itself, named after Vladimir Arnold, who demonstrated its effects in the 1960s using an image of a cat. Thought of as the quotient of the ordinary plane by the integer lattice, the map applies a simple linear transformation and then reduces the result modulo 1, folding everything that falls outside the unit square back inside it; it serves as a simple, pedagogical example of a hyperbolic toral automorphism.

Is Kind Of Object

Functions, Concepts

Entity-backed identity for the object-kind enum value this mathematical object already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The object-kind fact itself stays on the object unchanged.
