Plot of the Duffing map showing chaotic behavior, where a = 2.75 and b = 0.15.

The Duffing map (also called as 'Holmes map') is a discrete-time 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

x_{n+1}=y_{n}

y_{n+1}=-bx_{n}+ay_{n}-y_{n}^{3}.

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.
