Fatou Dust  

Robert P. Munafo, 2002 Apr 22.



A Julia set that is a Cantor set is called a Fatou dust. Such a Julia set has an infinite number of pieces, equal in number to a continuum, each of which is a single point, and no two "touch" each other.

All Fatou Dusts have a parameter that is not in the Mandelbrot set. See also Fundamental Dichotomy.

All embedded Julia sets are shaped like Fatou dusts. The Fatou dust in an embedded Julia set is a limit set of the nodes, which are connected to the Julia set's center by a binary tree of branching filaments. This structure is particularly evident in the Type CC embedded Julia sets, which are shaped like cauliflower Fatou dusts.
