Camacho, C. (ed.) et al., Complex analytic methods in dynamical systems. Proceedings of the congress held at Instituto de Matemática Pura e Aplicada, IMPA, Rio de Janeiro, Brazil, January 1992. Paris: Société Mathématique de France, Astérisque. 222, 201-231 (1994).
Approximate solutions of any polynomial equation with one variable can be obtained by Newton’s iteration method. This can be extended to the case of complex value equations by the study of iteration of rational functions. The extension was made also to the case of two variables.
In this paper the authors discuss global questions of iteration of rational maps in higher dimension. The analogue of Montel’s theorem comes from the Kobayashi hyperbolicity of the complement of certain complex hypersurfaces in the complex projective space of higher dimension. The authors discuss holomorphic maps, count the number of periodic points, describe the family of exceptional maps and classify critically finite maps of dimension two.
