Deterministic Chaos

6.D.5. Return Map

A return map plot of a sequence x₀, x₁, x₂, x₃, ... is a plot of the points

(x₀, x₁), (x₁, x₂), (x₂, x₃), (x₃, x₄), ...

Here is an illustration of the return using graphical iteration. Here is an explanation of the parts of this diagram.

To illustrate the sorts of things we can learn from a return map, here are some time series (left) and return maps (right).
