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

open access: yesMathematics, 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,

The radius of convexity of certain analytic functions II

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
In [2], MacGregor found the radius of convexity of the functions f(z)=z+a2z2+a3z3+…, analytic and univalent such that |f′(z)−1|

On Convex Univalent Functions with Convex Univalent Derivatives

open access: yesRocky Mountain Journal of Mathematics, 2005
The authors studied the functions \[ \sum_{k=0}^{\infty}a_{k}\dfrac{(1+z)^k}{k!}, \] for \(a_{0}\geq a_{1}\geq...\geq 0\). They showed that these functions are either constant or convex univalent in the unit disk \(D\). The work is inspired by \textit{T. J.

Univalent Monoidal Categories

open access: yesCoRR, 2022
Univalent categories constitute a well-behaved and useful notion of category in univalent foundations. The notion of univalence has subsequently been generalized to bicategories and other structures in (higher) category theory. Here, we zoom in on monoidal categories and study them in a univalent setting.

Properties of Functions Formed Using the Sakaguchi and Gao-Zhou Concept

open access: yesMathematics, 2020
This paper introduces a new class related to close-to-convex functions denoted by K s k , N . This class is based on combining the concepts of starlike functions with respect to N-ply symmetry points of the order α , introduced by ...

Brief Study On A New Family of Analytic Functions [PDF]

open access: yesSahand Communications in Mathematical Analysis
The authors introduced a new class of analytic functions in this study by means of convolution principle and obtain its relations with some well-known subclasses of analytic univalent functions in geometric functions theory in the open unit disk $\mathbb{

Several Subordination Features Using Bessel-Type Operator

open access: yesMathematics
For the function solution to the well-known homogeneous Bessel differential equation, we utilized a normalized form of this function to define a certain operator on a subclass of analytic functions.

Univalence of normalized solutions of W″(z)+p(z)W(z)=0

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1982
Denote solutions of W″(z)+p(z)W(z)=0 by Wα(z)=zα[1+∑n=1∞anzn] and Wβ(z)=zβ[1+∑n=1∞bnzn], where ...

Some Evaluations About Coefficients Boundaries for Specific Classes of Bi-Univalent Functions

open access: yesAxioms
New subclasses of bi-univalent functions with bounded boundary rotation are presented in this study. We acquired estimates for the initial coefficients a2, a3 and a4.
