Health indicators and human development in the Arab region

open access: yesInternational Journal of Health Geographics, 2006
Background The present paper deals with the relationship between health indicators and human development in the Arab region. Beyond descriptive analysis showing geographic similarities and disparities inter countries, the main purpose is to point out ...

Quantum–Fractal–Fractional Operator in a Complex Domain

open access: yesAxioms
In this effort, we extend the fractal–fractional operators into the complex plane together with the quantum calculus derivative to obtain a quantum–fractal–fractional operators (QFFOs).

Carathéodory properties of Gaussian hypergeometric function associated with differential inequalities in the complex plane

open access: yesAIMS Mathematics, 2021
<abstract><p>The results presented in this paper highlight the property of the Gaussian hypergeometric function to be a Carathéodory function and refer to certain differential inequalities interpreted in form of inclusion relations for subsets of the complex plane using the means of the theory of differential superordination and the method ...

Inequalities and Asymptotic Formulae for the Three Parametric Mittag-Leffler Functions [PDF]

open access: yes, 2012
MSC 2010: 33E12, 30A10, 30D15, 30E15We consider some families of 3-index generalizations of the classical Mittag-Le²er functions and study the behaviour of these functions in domains of the complex plane. First, some inequalities in the complex plane and

Some inequalities for rational function with prescribed poles and restricted zeros

open access: yesDemonstratio Mathematica
In this article, we first prove some auxiliary results in the form of lemmas using an improved Schwarz lemma at the boundary recently proved by Mercer. Furthermore, we establish some new inequalities for rational functions on the unit disk in the complex

Estimates of the Hyperbolic Radius Gradient and Schwarz–Pick Inequalities for the Eccentric Annulus [PDF]

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2016
Let Ω and Π be hyperbolic domains in the complex plane C. By A(Ω, Π) we shall designate the class of functions f which are holomorphic or meromorphic in Ω and such that f(Ω) ϲ Π.

Bell inequality with an arbitrary number of settings and its applications

open access: yes, 2006
Based on a geometrical argument introduced by Zukowski, a new multisetting Bell inequality is derived, for the scenario in which many parties make measurements on two-level systems. This generalizes and unifies some previous results.

Some conjectures about integral means of ∂f and ∂¯f [PDF]

open access: yes, 2011
The final version of the paper appears in: "Complex Analysis and Differential Equations" 64 (1999): 91-109. Print.We discuss some conjectural inequalities concerning a problem from the calculus of variations, namely that rank 1 convex functions are quasi-

Triangular ratio metric under quasiconformal mappings in sector domains

open access: yes, 2020
Hyperbolic metric and different hyperbolic type metrics are studied in open sector domains of the complex plane. Several sharp inequalities are proven for them.

On the super-energy radiative gravitational fields

open access: yes, 2013
We extend our recent analysis (Ferrando J J and S\'aez J A 2012 Class. Quantum Grav. 29 075012) on the Bel radiative gravitational fields to the super-energy radiative gravitational fields defined by Garc\'{\i}a-Parrado (Class. Quantum Grav.
