Abstract:A class of biholomorphic mappings named “quasi-convex mappings of type D” is introduced in the unit ball of a complex Banach space, which is the natural generalization of the convex functions in one variable. It is proved that this class of mappings is a subset of the class of “quasi-convex mappings of type A” introduced by K.A. Roper and T.J. Suffridge.
Keywords:Biholomorphic mapping   Locally biholomorphic mapping   Quasi-convex mappings   Convex mappings   Growth theorem
