Quadratic MapA 1-D Map often called ``the'' quadratic map is defined by

This is the real version of the complex map defining the Mandelbrot Set. The quadratic map is called attracting if theJacobian , and repelling if . Fixed Points occur when

The most general second-order 2-D Map with an elliptic fixed point at the origin has the form
The map must have a Determinant of 1 in order to be Area preserving, reducing the number of independent parameters from seven to three. The map can then be put in a standard form by scaling and rotating to obtain
The inverse map is
The Fixed Points are given by
