Fekete-Szegö inequalities for certain classes of biunivalent functions
Summary: We obtain the Fekete-Szegö inequalities for the classes \(S_{S, \Sigma}^*(\alpha, \phi)\) and \(\pounds_{S, \Sigma}(\alpha, \phi)\) of biunivalent functions denoted by subordination. The results presented in this paper improve the recent work of \textit{O. Crişan} [``Coefficient estimates for certain subclasses of bi-univalent functions'', Gen. Math. Notes 16, No. 2, 93--102 (2013)].
