On the Coefficients of Several Classes of Bi-Univalent Functions

Acta Mathematica Scientia, 2014
Abstract In this paper, we investigate the bounds of the coefficients of several classes of bi-univalent functions. The results presented in this paper improve or generalize the recent works of other authors.

A New Comprehensive Subclass of Analytic Bi-Univalent Functions Related to Gegenbauer Polynomials

Symmetry, 2023
In the current study, we provide a novel qualitative new subclass of analytical and bi-univalent functions in the symmetry domain U defined by the use of Gegenbauer polynomials.

COEFFICIENT BOUNDS FOR A SUBCLASS OF BI-UNIVALENT FUNCTIONS

, 2015
An 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.

Coefficient estimates for a certain subclass of analytic and bi-univalent functions

Applied Mathematics Letters, 2012
In this paper, we introduce and investigate an interesting subclass HΣh,p of analytic and bi-univalent functions in the open unit disk U. For functions belonging to the class HΣh,p, we obtain estimates on the first two Taylor–Maclaurin coefficients |a2 ...
