title: Fekete-Szegö Inequalities for Certain Classes of Biunivalent Functions.
abstract: We obtain the Fekete-Szegö inequalities for the classes S S,Σ (*)(α, ϕ) and £ S,Σ(α, ϕ) of biunivalent functions denoted by subordination. The results presented in this paper improve the recent work of Crisan (2013).
