| Research Abstract |
In the present research, through the study of special domains, we tried to give a higher-dimensional generalization of the Riemann mapping theorem that is a fundamental and important result in one complex variable. To be concrete, by making use the study of Reinhardt domains that are a kind of special domains, we succeeded in characterizing the direct product B of balls intrinsically by its holomorphic automorphism group when B is of some fundamental types. Also, related to this research, we established a systematic method of investigating the structure of a class of subgroups of the holomorphic automorphism group of the complex Euclidean space, and we obtained a lead to clarifying the structure of G itself.
