WebFor the Reaction-diffusion system, four matrices are initiated representing the amount of chemical A and chemical B in current state and next state. By following the finite solution of the system, the cells are updated one by one, or serially in each transverse. Weba combination of reaction and diffusion can generate spatial patterns (Turing 1952). In the paper, he studied the behaviour of a complex system in which two substances interact with each other and diffuse at different diffusion rates, which is known as the reaction–diffusion (RD) system. Turing proved mathematically that such system is

Mathematically, reaction–diffusion systems take the form of semi-linear parabolic partial differential equations. They can be represented in the general form where q(x, t) represents the unknown vector function, D is a diagonal matrix of diffusion coefficients, and R accounts for all local reactions. See more Reaction–diffusion systems are mathematical models which correspond to several physical phenomena. The most common is the change in space and time of the concentration of one or more chemical … See more The simplest reaction–diffusion equation is in one spatial dimension in plane geometry, $${\displaystyle \partial _{t}u=D\partial _{x}^{2}u+R(u),}$$ See more For a variety of systems, reaction–diffusion equations with more than two components have been proposed, e.g. the Belousov–Zhabotinsky reaction, … See more Well-controllable experiments in chemical reaction–diffusion systems have up to now been realized in three ways. First, gel reactors or filled … See more Two-component systems allow for a much larger range of possible phenomena than their one-component counterparts. An important idea that was first proposed by Alan Turing is that a state that is stable in the local system can become unstable in the presence of See more In recent times, reaction–diffusion systems have attracted much interest as a prototype model for pattern formation.
