Global stable manifold of the Lorenz system

Invariant manifolds of the Lorenz system

The Lorenz system is the three-dimensional vector field

 

\begin{array}{rcl} \{\dot x &=& \sigma (y-x) \ \dot y &=& \varrho x - y -xz \ \dot z &=& xy - \beta z, \end{array}

 

We choose the standard parameter values parameters: \(\sigma=10\), \(\rho=28\), but take \(\beta=0.4\). The two-dimensional stable manifold of the origin interacts now with an attracting periodic orbit. The colored bands on the manifold show the steps that are taken by the algorithm. Note how the algorithm slows down each time a new helix around the \(z\)-axis is being formed.
