He. Nusse et Ja. Yorke, Fractal basin boundaries generated by basin cells and the geometry of mixing chaotic flows, PHYS REV L, 84(4), 2000, pp. 626-629
Experiments and computations indicate that mixing in chaotic flows generate
s certain coherent spatial structures. Lf a two-dimensional basin has a bas
in cell (a trappings region whose boundary consists of pieces of the stable
and unstable manifold of some periodic orbit) then the basin consists of a
central body (the basin cell) and a finite number of channels: attached to
it and the basin boundary is fractal. We demonstrate an amazing property f
or certain global structures: A basin has a basin cell if and only if every
diverging curve comes close to every basin boundary point of that basin.
