Fekete-Szeg? Functional Problems for Certain Subclasses of Bi-Univalent Functions Involving the Hohlov Operator

摘要

In the paper the new subclasses ■ and ■ of the function class ∑ of bi-univalent functions involving the Hohlov operator are introduced and investigated.Then, the corresponding Fekete-Szeg functional inequalities as well as the bound estimates of the coefficients a2 and a3 are obtained. Furthermore, several consequences and connections to some of the earlier known results also are given.
