Coefficient Estimates for Meromorphic Bi-Univalent Functions

Abstract

A univalent meromorphic function defined on $\Delta :=\{z\in \mathbb{C}:1<|z|<\infty \}$ with univalent inverse defined on $\Delta$ is bi-univalent meromorphic in $\Delta$. For certain subclasses of meromorphic bi-univalent functions, estimates on the initial coefficients are obtained.
