A strong convergence theorem on solving common solutions for generalized equilibrium problems and fixed-point problems in Banach space [PDF]

open access: yesFixed Point Theory and Applications, 2011
In this paper, the common solution problem (P1) of generalized equilibrium problems for a system of inverse-strongly monotone mappings and a system of bifunctions satisfying certain conditions, and the common fixed-point problem (P2) for a family of ...

A new interpretation of Jensen's inequality and geometric properties of φ -means

open access: yesJournal of Inequalities and Applications, 2011
We introduce a mean of a real-valued measurable function f on a probability space induced by a strictly monotone function φ. Such a mean is called a φ-mean of f and written by Mφ (f).

Convexity-preserving properties of set-valued ratios of affine functions [PDF]

open access: yes, 2021
The aim of this paper is to introduce some classes of set-valued functions that preserve the convexity of sets by direct and inverse images. In particular, we show that the so-called set-valued ratios of affine functions represent such a class.

Fractional Hadamard and Fej´er-Hadamard inequalities for exponentially m-convex function [PDF]

open access: yes, 2021
Fractional integral operators play a vital role in the advancement of mathematical inequalities. The aim of this paper is to present the Hadamard and the Fej´er-Hadamard inequalities for generalized fractional integral operators containing Mittag-Leffler

A new refinement of Jensen’s inequality with applications in information theory

open access: yesOpen Mathematics, 2020
In this paper, we present a new refinement of Jensen’s inequality with applications in information theory. The refinement of Jensen’s inequality is obtained based on the general functional in the work of Popescu et al.

On Hermite-Hadamard-type inequalities for systems of partial differential inequalities in the plane

open access: yesOpen Mathematics, 2023
We establish necessary conditions for the existence of solutions to various systems of partial differential inequalities in the plane. The obtained conditions provide new Hermite-Hadamard-type inequalities for differentiable functions in the plane.

About the B-concavity of functions with many variables

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023
The paper deals with the study of the property of B-concavity and BB concavity in the bi-dimesional case and with the relation between these properties and the Bernstein operators defined on a simplex.

Sandwich Type Results For m-Convex Real Functions

open access: yesAnnales Mathematicae Silesianae, 2021
We establish necessary and sufficient conditions allowing separation of pair of real functions by an m-convex and by an m-affine function. Some examples and a geometric interpretation of m-convexity of a function is exhibited, as well as a Jensen’s ...

New fractional integral inequalities via Euler's beta function

open access: yesOpen Mathematics, 2023
In this article, we present new fractional integral inequalities via Euler’s beta function in terms of ss-convex mappings. We develop some new generalizations of fractional trapezoid- and midpoint-type inequalities using the class of differentiable ss ...
