Bézier-Summation-Integral-Type Operators That Include Pólya–Eggenberger Distribution

open access: yesMathematics, 2022
We define the summation-integral-type operators involving the ideas of Pólya–Eggenberger distribution and Bézier basis functions, and study some of their basic approximation properties. In addition, by means of the Ditzian–Totik modulus of smoothness, we

On the Approximation Properties of q−Analogue Bivariate λ‐Bernstein Type Operators

open access: yesJournal of Function Spaces, Volume 2020, Issue 1, 2020., 2020
In this article, we establish an extension of the bivariate generalization of the q‐Bernstein type operators involving parameter λ and extension of GBS (Generalized Boolean Sum) operators of bivariate q‐Bernstein type. For the first operators, we state the Volkov‐type theorem and we obtain a Voronovskaja type and investigate the degree of approximation

Modified Bernstein–Durrmeyer Type Operators

open access: yesMathematics, 2022
We constructed a summation–integral type operator based on the latest research in the linear positive operators area. We establish some approximation properties for this new operator.

Weighted Simultaneous Approximation of the Linear Combinations of Baskakov Operators

open access: yesComplexity, Volume 2020, Issue 1, 2020., 2020
In this paper, the approximation property of the linear combinations of Baskakov operators is investigated by using a Jacobi weight function. Moreover, both the positive and inverse theorems for the weighted simultaneous approximation of the linear combinations of Baskakov operators are proved.

On the order of approximation by modified summation-integral-type operators based on two parameters

open access: yesDemonstratio Mathematica, 2023
In this article, we the study generalized family of positive linear operators based on two parameters, which are a broad family of many well-known linear positive operators, e.g., Baskakov-Durrmeyer, Baskakov-Szász, Szász-Beta, Lupaş-Beta, Lupaş-Szász ...

A Note on Two Moduli of Smoothness [PDF]

open access: yes, 1995
We prove that for f ∈ Lp[−1, 1], 0 < p < 1 the modulus of smoothness τk(f, Δn)p,p introduced by Ivanov and Ditzian-Totik modulus of smoothness ωkφ(f, n−1)p are ...

Some approximation properties of ( p , q ) $(p,q)$ -Bernstein operators

open access: yesJournal of Inequalities and Applications, 2016
This paper is concerned with the ( p , q ) $(p,q)$ -analog of Bernstein operators. It is proved that, when the function is convex, the ( p , q ) $(p,q)$ -Bernstein operators are monotonic decreasing, as in the classical case.

On the sharpness of a Jackson estimate by Ditzian-Totik [PDF]

open access: yes, 1996
Using ideas of Grünwald, Marcinkiewicz, and Vértesi concerning the divergence of interpolation processes, a counterexample is constructed which establishes that a Jackson estimate for the best approximation by algebraic polynomials given by Ditzian and ...

Pointwise Approximation for Linear Combinations of Bernstein Operators [PDF]

open access: yes, 2000
For linear combinations of Bernstein operators Bn, r(f, x), we give an equivalent theorem with ω2rφλ(f, t), where ω2rφλ(f, t) is the Ditzian–Totik modulus of smoothness (1−1/r⩽λ⩽1). It is the generalization of corresponding results by Z.
