Quantitative estimations of bivariate summation‐integral–type operators

Mathematical Methods in the Applied Sciences, 2019
In this paper, we study the approximation properties of bivariate summation‐integral–type operators with two parameters . The present work deals within the polynomial weight space. The rate of convergence is obtained while the function belonging to the set of all continuous and bounded function defined on ([0],∞)(×[0],∞) and function belonging to the ...

Bivariate Cheney-Sharma operators on simplex

2016
In this paper, we consider bivariate Cheney-Sharma operators which are not the tensor product construction. Precisely, we show that these operators preserve Lipschitz condition of a given Lipschitz continuous function f and also the properties of the modulus of continuity function when f is a modulus of continuity function.

Bivariate q-Bernstein–Chlodowsky–Durrmeyer type operators and the associated GBS operators

Asian-European Journal of Mathematics, 2019
This paper deals with the approximation properties of the [Formula: see text]-bivariate Bernstein–Chlodowsky operators of Durrmeyer type. We investigate the approximation degree of the [Formula: see text]-bivariate operators for continuous functions in Lipschitz space and also with the help of partial modulus of continuity.

Bivariate Extension of Linear Positive Operators

2016
The goal of this chapter is to present a survey of the literature on approximation of functions of two variables by linear positive operators. We study the approximation properties of these operators in the space of functions of two variables, continuous on a compact set. We also discuss the convergence of the operators in a weighted space of functions

On nonlinear bivariate singular integral operators

Mathematical Methods in the Applied Sciences, 2018
In this paper, we give some pointwise convergence and Fatou type convergence theorems for a family of nonlinear bivariate singular integral operators in the following form: urn:x-wiley:mma:media:mma5425:mma5425-math-0006 where m1,m2  ≥  1 are fixed natural numbers, and ω  ∈  Ω, Ω denotes a nonempty set of indices endowed with a topology.

Bivariate copula-based aggregation operators

2007
This paper presents the role of copulafunc- tions in the theory of aggregation operators. In this context we are focusing our attention abouts everal properties of aggregation functions,like supermodularity andSchur- concavity, studying also a decompositionof supermodular binary aggregation operators and copulae.
