New classes of bi-univalent functions

Journal of Interdisciplinary Mathematics, 2020
This paper tends to investigate a few new subclasses of bi-univalent functions H(v, λ, n) as well as G(v, ξ, n) in an open disc U of unit length.

ON SOME CLASSES OF BI-UNIVALENT FUNCTIONS

1988
Let S denote the class of all functions \(f(z)=z+a_ 2z^ 2+a_ 3z^ 3+..\). which are analytic and univalent in the unit disc \(U=\{z:| z|

Coefficient bounds for a subclass of Bi-univalent functions

Acta Universitatis Apulensis, 2014
Summary: In the present investigation, we introduce two new subclasses \(ST_\Sigma(b,\phi)\) and \(CV_\Sigma(b,\phi)\) of bi-univalent functions defined in the open unit disc \(\mathbb U=\{z:| z|

New subclasses of bi-univalent functions involving polylogarithm functions

AIP Conference Proceedings, 2014
In the present paper, we introduce two new subclasses of the function class Σ of bi-univalent functions involving polylogarithm functions defined in the open unit disc U = :{z:z∈C,|z|

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.
