A Turing pattern is a spatially structured state produced by interactions between local reactions and diffusion. A Turing instability explains linear pattern onset when a homogeneous equilibrium is stable without diffusion but unstable to a nonzero spatial mode.
A Turing pattern refers to a mathematical model that describes how complex patterns can emerge in biological systems through the interaction of two or more substances that diffuse and react with each other. This concept was introduced by the British mathematician and logician Alan Turing in his 1952 paper titled "The Chemical Basis of Morphogenesis.
