Abstract: In this article, we mainly study the invariance of some biholomorphic mappings with special geometric characteristics under the extension operators. First we generalize the Roper-Suffridge extension operators on Bergman-Hartogs domains. Then, by the geometric characteristics of subclasses of biholomorphic mappings, we conclude that the modified Roper-Suffridge operators preserve the properties of SΩ*Ω(β, A, B), parabolic and spirallike mappings of type β and order ρ, strong and almost spirallike mappings of type β and order α as well as almost starlike mappings of complex order λ on Ωp1Bn,…,ps,q under different conditions, respectively. The conclusions provide new approaches to construct these biholomorphic mappings in several complex variables.

Key words: spirallike mappings, Roper-Suffridge operator, Bergman-Hartogs domains
