7d: What are some Julia set facts?

The Julia set of any rational map of degree greater than one is perfect
(hence in particular uncountable and nonempty), completely invariant, equal
to the Julia set of any iterate of the function, and also is the boundary
of the basin of attraction of every attractor for the map.

Dynamical Systems_, Springer-Verlag, New York, 1991.

the Amer. Math. Soc_ 11, 1 (July 1984), pp. 85-141. This article is a
detailed discussion of the mathematics of iterated complex functions. It
covers most things about Julia sets of rational polynomial functions.
