In this paper,we define the class■ of g-parametric star like mappings of real order γ on the unit ball BX in a complex Banach space X,where g is analytic and satisfies certain conditions.By establishing the distortion theorem of the Fréchet-derivative type of■ with a weak restrictive condition,we further obtain the distortion results of the Jacobi-determinant type and the Fréchet-derivative type for the corresponding classes(compared with■) defined on the unit polydisc(resp.unit ball ... 相似文献
