... The study of iterations of rational mappings of the Riemann sphere was started at the end of 19-th - beginning of 20th century, in the works of Fatou and Julia. ... R.Mane, P.Sad and D.Sullivan have proved in their joint paper [M] that each hyperbolic mapping is structurally stable on its Julia set: the mapping and its small perturbation (in the class of rational mappings of the same degree) are conjugated on their Julia sets by a homeomorphism}. ...
