Faber polynomial coefficient estimates for a subclass of analytic bi-univalent functions defined by S\u{a}l\u{a}gean differential operator
Serap Bulut

Abstract

In this work, considering a subclass of analytic bi-univalent functions defined by S\u{a}l\u{a}gean differential operator, we determine estimates for the general Taylor-Maclaurin coefficients of the functions in this class. For this purpose, we use the Faber polynomial expansions. In certain cases, our estimates improve some of existing coefficient bounds.
