Applications of the Hadamard product in geometric function theory
Let denote the set of functions holomorphic in the unit disc, normalized clasically: , whereas is an arbitrarily fixed subset. In this paper various properties of the classes , of functions of the form are studied, where , , and denotes the Hadamard product of the functions and . Some special cases of the set were considered by other authors (see, for example, [15],[6],[3]).
