Abstract.
It is known that all origin-preserving automorphisms of quasi-circular domains are polynomial mappings. By introducing the "resonance order" and "quasi-resonance order", we provide the optimal uniform upper bound for the degree of such mappings. We will also discuss the problem from the point of view of Bergman representative coordinates.
