| 摘 要： | Let C be the familiar class of normalized close-to-convex functions in the unit disk.In 17],Koepf demonstrated that,as to a function ■ in the class C,■By applying this inequality,it can be proven that ‖a3|-|a2‖≤ 1 for close-to-convex functions.Now we generalized the above conclusions to a subclass of close-to-starlike mappings defined on the unit ball of a complex Banach space.
