On the convergence of Lupaş (p,q) $(p,q)$-Bernstein operators via contraction principle
Journal of Inequalities and Applications, 2019 The present paper deals with the limit behavior of iterates of Lupaş q- and (p,q) $(p,q)$-Bernstein operators. We obtain the convergence for Lupaş q- and (p,q) $(p,q)$-Bernstein operators by using the contraction principle.

Statistical Convergence of Bernstein Operators
Applied Mathematics & Information Sciences, 2016 The Bernstein operator is one of the important topics of approximation theory in which it has been studied in great details for a long time. The aim of this paper is to study the statistical convergence of sequence of Bernstein polynomials. In this paper, we introduce the concepts of statistical convergence of Bernstein polynomials and VB−summability ...

Bivariate Chlodowsky-Stancu Variant of (p,q)-Bernstein-Schurer Operators
Journal of Function Spaces, 2019 In this study, it is proposed to define bivariate Chlodowsky variant of (p,q)-Bernstein-Stancu-Schurer operators. Therefore, Korovkin-type approximation theorems and the error of approximation by using full modulus of continuity are presented.

Spectral analysis of subordinate Brownian motions in half-line
, 2011 We study one-dimensional Levy processes with Levy-Khintchine exponent psi(xi^2), where psi is a complete Bernstein function. These processes are subordinate Brownian motions corresponding to subordinators, whose Levy measure has completely monotone ...

The generalization of Voronovskaja's theorem for a class of linear and positive operators
Journal of Numerical Analysis and Approximation Theory, 2005 In this paper we generalize Voronovskaja's theorem for a class of linear and positive operators, and then, through particular cases, we obtain statements verified by the Bernstein, Schurer, Stancu, Kantorovich and Durrmeyer operators.

On Durrmeyer Type λ-Bernstein Operators via (p, q)-Calculus
Journal of Function Spaces, 2020 In the present paper, Durrmeyer type λ-Bernstein operators via (p, q)-calculus are constructed, the first and second moments and central moments of these operators are estimated, a Korovkin type approximation theorem is established, and the estimates on ...

ψ‐Bernstein–Kantorovich operators
Mathematical Methods in the Applied SciencesIn this article, we introduce a modified class of Bernstein–Kantorovich operators depending on an integrable function and investigate their approximation properties. By choosing an appropriate function , the order of approximation of our operators to a function is at least as good as the classical Bernstein–Kantorovich operators on the interval .

Growth of Omnichannel Grocery Retailing and Food Prices
Agribusiness, EarlyView.ABSTRACT This paper examines the effects of the growth of omnichannel grocery retailing on food prices. We first develop a conceptual model of consumer choice and retailer pricing that allows us to evaluate changes in equilibrium prices, quantities, and profits with online channel growth and alternative pricing strategies.
