Löwner chains and a subclass of bi-univalent functions

Georgian Mathematical Journal, 2022
Abstract In this paper, we give characterization of subclasses of bi-univalent functions and also consider bi-starlike functions on the unit disk in ℂ in terms of Löwner chains.

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.

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.
