Gamma-Bazilevič Functions

Mathematics, 2020
For γ ≥ 0 and α ≥ 0 , we introduce the class B 1 γ ( α ) of Gamma−Bazilevič functions defined for z ∈ D by R e z f ′ ( z ) f ( z ) 1 − α

Second Hankel Determinant for Certain Subclasses of Bi-univalent functions

Journal of Physics: Conference Series, 2020
In this paper, we have investigated the upper bound for the second hankel determinant for some subclasses of bi-univalent functions in open unit disc U by using Chebyshev polynomials.

Univalent Logharmonic Mappings in the Plane

Abstract and Applied Analysis, 2012
This paper surveys recent advances on univalent logharmonic mappings defined on a simply or multiply connected domain. Topics discussed include mapping theorems, logharmonic automorphisms, univalent logharmonic extensions onto the unit disc or the ...

Univalent functions having univalent derivatives [PDF]

Rocky Mountain Journal of Mathematics, 1986
Let T denote the family of functions \(f(z)=z-\sum^{\infty}_{n=2}a_ nz^ n\), \(a_ n\geq 0\), which are analytic and univalent in the unit disk \(\Delta =\{| z|

Bi-Univalent Problems Involving Generalized Multiplier Transform with Respect to Symmetric and Conjugate Points

Fractal and Fractional, 2022
In the present article, using the subordination principle, the authors employed certain generalized multiplier transform to define two new subclasses of analytic functions with respect to symmetric and conjugate points.

Faber Polynomial Coefficient Estimates for Bi-Univalent Functions Defined by Using Differential Subordination and a Certain Fractional Derivative Operator

Mathematics, 2020
In this article, we introduce a general family of analytic and bi-univalent functions in the open unit disk, which is defined by applying the principle of differential subordination between analytic functions and the Tremblay fractional derivative ...

Segregation of the univalent X chromosome in the wide-footed treehopper Enchenopa latipes (Say 1824)

Caryologia, 2022
In metaphase I, autosomal bivalents align on the metaphase plate, while naturally-occurring univalent sex chromosomes can display a number of different behaviours depending on cellular conditions.

New Subclass of Convex Functions Concerning Infinite Cone [PDF]

Sahand Communications in Mathematical Analysis
We introduce a new subclass of convex functions as follows:\[  \mathcal{K}_{IC}:=\left\{f\in \mathcal{A}:{\rm  Re}\left(1+\frac{zf''(z)}{f'(z)}\right)>\left|f'(z)-1\right|,\quad  |z|

Hölder Inequalities for a Generalized Subclass of Univalent Functions Involving Borel Distributions

Mathematics, 2022
In this article, by making use of the Borel distributions series, we introduce a new family of normalized holomorphic functions in the open unit disk and investigate necessary and sufficient conditions for functions f to be in this new class. Furthermore,
