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.

ψ‐Bernstein–Kantorovich operators

Mathematical Methods in the Applied Sciences
In 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 .

Optimality of generalized Bernstein operators

Journal of Approximation Theory, 2010
We show that a certain optimality property of the classical Bernstein operator also holds, when suitably reinterpreted, for generalized Bernstein operators on extended Chebyshev systems.

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.

Approximation properties of Chlodowsky variant of ( p , q ) $(p,q)$ Bernstein-Stancu-Schurer operators

Journal of Inequalities and Applications, 2017
In the present paper, we introduce the Chlodowsky variant of ( p , q ) $(p,q)$ Bernstein-Stancu-Schurer operators which is a generalization of ( p , q ) $(p,q)$ Bernstein-Stancu-Schurer 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 ...

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.

Consumer Acceptance of New Sustainable Food Technologies: Upcycling Technology, Biostimulants, and Artificial Intelligence

Agribusiness, EarlyView.
ABSTRACT Food systems have a significant impact on environmental sustainability, underscoring the need for innovative technologies to support more sustainable agricultural methods. However, the adoption of these technologies hinges on consumer acceptance, making the analysis of consumer perceptions essential.
