General Interest:Higher Dimensional Objects

4-d Map by Eduardo Tabacman

Two 2-dimensional surfaces in 4D, projected to 3D. (The color, from green to blue, represents the fourth coordinate). The surfaces are points in R^4 that converge (for stable manifold) to a fixed point (roughly in the middle of the surfaces) under iteration of a symplectic map, or diverge (for unstable one).

How to make it: Made by iteration of a (small) grid around the fixed point, in the directions of the eigenvectors of the Jacobian of the map. Viewed with geomview (4d-module).
