Estimate of third Hankel determinant for a subfamily of analytic functions

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2023
In this article, our aim is to study analytic functions related with Salagean operator and associated with the right half of the lemniscate of Bernoulli. We find the estimates of the third Hankel determinant for new family of analytic functions.

CERTAIN PROPERTIES OF AN OPERATOR INVOLVING SUBORDINATION

open access: yesПроблемы анализа, 2015
The concept of subordination can be traced back to LindelÄof since 1909, but other mathematicians like Littlewood (1925) and Rogosinski (1939) introduced the term and developed the basic theories.

On Geometric Properties of Bessel–Struve Kernel Functions in Unit Disc

open access: yesMathematics, 2022
The Bessel–Struve kernel function defined in the unit disc is used in this study. The Bessel–Struve kernel functions are generalized in this article, and differential equations are derived.

On the range of subordinators

open access: yesElectronic Communications in Probability, 2014
In this note we look into detail at the box-counting dimension of subordinators. Given that $X$ is a non-decreasing Levy process, which is not a compound Poisson process, we show that in the limit, the minimum number of boxes of size $δ$ that cover the range of $(X_s)_{s\leq t}$ is a.s.

Fundamental rights and private law:<br> A relationship of subordination or complementarity?

open access: yesUtrecht Law Review, 2007
Originally, private law was considered to be immune from the effect of fundamental rights, the function of which was limited to being individual defences against the vigilant eye of the state.

Applications of Beta Negative Binomial Distribution and Laguerre Polynomials on Ozaki Bi-Close-to-Convex Functions

open access: yesAxioms, 2022
In the present paper, due to beta negative binomial distribution series and Laguerre polynomials, we investigate a new family FΣ(δ,η,λ,θ;h) of normalized holomorphic and bi-univalent functions associated with Ozaki close-to-convex functions.

Properties of Differential Subordination and Superordination for Multivalent Functions Associated with the Convolution Operators

open access: yesAxioms, 2023
Using convolution (or Hadamard product), we define the El-Ashwah and Drbuk linear operator, which is a multivalent function in the unit disk U=w ...

Differential and fuzzy differential sandwich theorems involving quantum calculus operators

open access: yesJournal of Nigerian Society of Physical Sciences
The principle of subordination is useful in comparing two holomorphic functions when the range of one holomorphic function is a subset of the other and they comply at a single point.

Inclusion Properties on a Class of Meromorphic Functions Defined by a Linear Operator

open access: yesJournal of Mathematical and Fundamental Sciences, 2016
In the present paper, we study a certain class of meromorphic univalent functions f(z) dened by the linear operator L(α,β) f (z). The aim of the present paper is to prove some properties for the class Σα,β,kλ;(h) to satisfy the certain subordination ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
