Coefficient estimates for a subclass of analytic bi-univalent functions
2018Summary: In this work, we use the Faber polynomial expansions to find upper bounds for the coefficients of analytic bi-univalent functions in subclass \( \Sigma(\tau,\gamma,\phi)\) which is defined by subordination conditions in the open unit disk \(\mathbb{U}\). In certain cases, our estimates improve some of those existing coefficient bounds.

COEFFICIENT BOUNDS FOR A SUBCLASS OF BI-UNIVALENT FUNCTIONS
2015An analytic function f defined on the open unit disk U = {z : vertical bar z vertical bar < 1} is biunivalent if the function f and its inverse f(-1) are univalent in U. Inspired by the recent work of Hamidi et al. [8], we propose to investigate the coefficient estimates for a general class of analytic and bi-univalent functions.
