Coefficient Estimates for a Subclass of Bi-univalent Functions
Coefficient Estimates for a Subclass of Bi-univalent Functions
In this paper, we consider a subclass $S_{\Sigma}(\alpha,\beta)$ of bi-univalent functions defined in the open unit disk $D=\lbrace z\in\mathbb{C}:|z|< 1\rbrace$. Besides, we find upper bounds for the second and third coefficients for functions in this subclass.
