Faber Polynomial Coefficient Estimates for aComprehensive Subclass of Analytic Bi-Univalent Functions Defined by Subordination

In this paper, we find coefficient estimates by a new method making use of the Faber polynomial expansions for a comprehensive subclass of analytic bi-univalent functions, which is defined by subordinations in the open unit disk. The coefficient bounds presented in this paper would generalize and improve some recent works appeared in the literature.
