Inequalities and approximation theory
Abstract The purpose of this paper is twofold. Firstly, we present an equivalence property involving isotonic linear functionals. Secondly, by…
Application of Popoviciu’s high convexity to the study of some sequences properties
Abstract Starting by the notion of convex funcitons of \(n\)-order introduced by Tiberiu Popoviciu, we aim to record those theorems…
More than a summing up about Meyer-Konig and Zeller operators
Abstract In this paper we bring together the most outstanding results concerning the Meyer-Konig and Zeller operators. Furthermore, a generalization…
A generalization of Durrmeyer-type polynomials and their approximation
Abstract We propose a general class of polynomials investigating the convergence of the operators constructed on the basis of these…
Linear operators generated by a probability density function
Abstract In this paper we deal with linear positive operators of both discrete and integral type. For the former we…
