Quantitative Estimates for the Tensor Product (p,q)-Balázs-Szabados Operators and Associated Generalized Boolean Sum Operators

Filomat, 2020
In this study, we give some approximation results for the tensor product of (p,q)-Bal?zs-Szabados operators associated generalized Boolean sum (GBS) operators. Firstly, we introduce tensor product (p,q)-Bal?zs-Szabados operators and give an uniform convergence theorem of these operators on compact rectangular regions with an illustrative ...

Approximation by Tensor-Product Kind Bivariate Operator of a New Generalization of Bernstein-Type Rational Functions and Its GBS Operator

Mathematics, 2022
We introduce a tensor-product kind bivariate operator of a new generalization of Bernstein-type rational functions and its GBS (generalized Boolean sum) operator, and we investigate their approximation properties by obtaining their rates of convergence ...

On the rate of convergence of modified \(\alpha\)-Bernstein operators based on q-integers

Journal of Numerical Analysis and Approximation Theory, 2022
In the present paper we define a q-analogue of the modified a-Bernstein operators introduced by Kajla and Acar (Ann. Funct. Anal. 10 (4) 2019, 570-582). We study uniform convergence theorem and the Voronovskaja type asymptotic theorem.

A Korovkin-type theorem for generalizations of Boolean sum operators and approximation by trigonometric pseudopolynomials

Journal of Numerical Analysis and Approximation Theory, 1988
A real-valued function f on \(D\subset {\mathbb{R}}^ 2\) is called B- continuous if for every (x,y)\(\in D\) we have \(\lim_{(u,\nu)\to (x,y)}\Delta_{u,\nu}f(x,y)=0\) where \[ \Delta_{u,\nu}f(x,y)=f(x,y)- f(x,\nu)-f(u,y)+f(u,\nu). \] In this paper an analogue to Korovkin-type theorem, for the approximation of certain ``periodic'' functions satisfyng \(\
