Fekete-Szego Inequalities for Certain Subclasses of Bi-Univalent Functions

Show other versions (1)

In this paper, we consider the subclasses H-sigma(a,b;c)(phi) and B-sigma(a,b;c)(phi, lambda) of bi-univalent functions associated with the Hohlov operator. These subclasses are defined in terms of subordination. The Fekete-Szego inequalities are determined and some previous results can be obtained...

Description
Summary:In this paper, we consider the subclasses H-sigma(a,b;c)(phi) and B-sigma(a,b;c)(phi, lambda) of bi-univalent functions associated with the Hohlov operator. These subclasses are defined in terms of subordination. The Fekete-Szego inequalities are determined and some previous results can be obtained using these findings.
