Fekete-Szegö inequalities for certain subclasses of bi-univalent functions

Show other versions (1)

In this paper, we consider the subclasses Ha,b,cσ (φ) and Ba,b,cσ(φ,λ) of bi-univalent functions associated with the Hohlov operator. These subclasses are defined in terms of subordination. The Fekete-Szeg... inequalities are determined and some previous results can be obtained using these findings....
