Gauss iterated map

Cobweb plot of the Gauss map for \alpha=4.90 and \beta=-0.58. This shows an 8-cycle.

In mathematics, the Gauss map (also known as Gaussian map[1] or mouse map), is a nonlinear iterated map of the reals into a real interval given by the Gaussian function:

x_{n+1} = \exp(-\alpha x^2_n)+\beta, \,

where α and β are real parameters.

Named after Johann Carl Friedrich Gauss, the function maps the bell shaped Gaussian function similar to the logistic map.


Properties

In the parameter real space x_n can be chaotic. The map is also called the mouse map because its bifurcation diagram resembles a mouse (see Figures).
