Initial Maclaurin Coefficients Bounds for New Subclasses of Bi-univalent Functions

Abstract

In this work we introduce the subclasses L(theta, alpha) and L(theta, gamma) of bi-univalent functions. Furthermore, we obtain coefficient bounds involving the Taylor-Maclaurin coefficients a2 and a3 for functions belonging to these classes. The results presented in this paper would generalize those in related works of several earlier authors.
