Two Inclusive Subfamilies of bi-univalent Functions

International Journal of Neutrosophic Science
The aim of this article is to establish two new and qualitative subfamilies F(ε, κ, ℵ) and G(ε, κ, ℵ) of biunivalent functions. For functions in these subfamilies, we determine the first two Maclaurin coefficient estimations |C2| and |C3|, and address the Fekete–Szeg¨o problem. Additionally, we mention some corollaries related to the main results.

Coefficient estimates for a subclass of analytic bi-univalent functions

2018
Summary: 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.

FABER POLYNOMIAL COEFFICIENTS ESTIMATES OF BI-UNIVALENT FUNCTIONS

In our present investigation, we use the Faber polynomial expansions to find upper bounds for the n ? th (n ? 4) coefficients of general subclass of analytic bi-univalent functions. In certain cases, our estimates improve some of those existing coefficient bounds. © 2020, Bayram Sahin. All rights reserved.
