The Duffing map (also called as 'Holmes map') is a discretetime dynamical system. It is an example of a dynamical system that exhibits chaotic behavior. The Duffing map takes a point (x_{n}, y_{n}) in the plane and maps it to a new point given by
The map depends on the two constants a and b. These are usually set to a = 2.75 and b = 0.2 to produce chaotic behaviour. It is a discrete version of the Duffing equation.
