For a rational map f: [P.sup.1.sub.K] [right arrow] [P.sup.1.sub.K], the Fatou set is defined as the largest open set of [P.sup.1.sub.K] on which [{[f.sup.k]}.sup.[infinity].sub.
The complementary of J(R) in the Riemann sphere is the Fatou set F(R).
The dynamics of this rational map induces a subdivision of the complex sphere into two sets, namely, the Fatou set F(R) and the Julia set J(R) of R.
Definition: The set of all orbits that either converge to a value or diverge (which can also be considered converging to infinity) is called the Fatou set. The complement of the Fatou set is the Julia set.
