| Research Abstract |
We investigeted complex dynamical system defind by holo-morphic maps of a complex projective space onto itself, as a generalization of the iteration theory of rational function of one complex variable.
The Fatou set is defined to be the maximal open set on which the family of the iterates of such a holomorphic map constitute a normal family. This is considered as one of the most fundamental object in the theory. In our study we have proved that the Fatou set os pseudoconvex and hence a Stain open set, and further that follows that, every basin of attraction of an attracting periodic point or that of parabolic periodic point contains a critical point.
We have also given some examples of dynamical systems ori pro-jective planes for which the Fatou set can be concretely described using elliptic functions, and for which the Fatou set is empty.
Further we studied the ralation among the Fatou set, the forward orbit of the set of the critical points and its limit set set. In particular, we stydied the critically finite case, i.e., the case for which the orbit of the the set of the critical points is an algebraic set. For the case of dimension 2, we have given the condi-tion for the Fatou set is empty.
