Coefficient Bounds And Fekete-Szegӧ Problem For A New Subclasses Of Holomorphic Bi-Univalent Functions Defined By Horadam Polynomials, Najah Ali Jiben Al-Zaidi, Abbas Kareem Wanas
Al-Qadisiyah Journal of Pure Science
In the present paper, by making use the Horadam polynomials, we introduce and investigate two new subclasses and of the function class of holomorphic bi-univalent functions in the open unit disk Δ. For functions belonging to this subclasses, we obtain upper bounds for the second and third coefficients and discuss Fekete-Szegӧ problem. Furthermore, we point out several new special cases of our results.

Al-Qadisiyah Journal of Pure Science
The purpose of this paper, is to present differential operator for the univalent functions employ a Faber Polynomial . In addition, we will introduce some inclusion properties of the operator that were obtained employ the principle of subordination between holomorphic functions.
