On Becker's univalence criterion [PDF]

open access: yes, 2017
We study locally univalent functions $f$ analytic in the unit disc $\mathbb{D}$ of the complex plane such that $|{f"(z)/f'(z)}|(1-|z|^2)\leq 1+C(1-|z|)$ holds for all $z\in\mathbb{D}$, for some ...

Univalent Logharmonic Mappings in the Plane

open access: yesAbstract 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]

open access: yesRocky 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|

On some geometric results for generalized k-Bessel functions

open access: yesDemonstratio Mathematica, 2023
The main aim of this article is to present some novel geometric properties for three distinct normalizations of the generalized kk-Bessel functions, such as the radii of uniform convexity and of α\alpha -convexity.

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

open access: yesCaryologia, 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.

Asymmetric switch costs in numeral naming and number word reading: Implications for models of bilingual language production [PDF]

open access: yes, 2016
One approach used to gain insight into the processes underlying bilingual language comprehension and production examines the costs that arise from switching languages.

New Subclass of Convex Functions Concerning Infinite Cone [PDF]

open access: yesSahand 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|

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

open access: yesFractal 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.

Coefficient Estimates for Certain Classes of Bi-Univalent Functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2013
A function analytic in the open unit disk is said to be bi-univalent in if both the function and its inverse map are univalent there. The bi-univalency condition imposed on the functions analytic in makes the behavior of their coefficients ...
