Bounds for initial MacLaurin coefficients of a subclass of bi-univalent functions associated with subordination

Abstract

In this paper, we investigate the bounds of the coefficients for new subclasses of analytic and bi-univalent functions in the open unit disc defined by subordination. The coefficients bounds presented in this paper would generalize and improve those in related works of several earlier authors

Keywords
