A Voronovskaja-Type Theorem for a Kind of Durrmeyer-Bernstein-Stancu Operators

GAZI UNIVERSITY JOURNAL OF SCIENCE, 2019
In this paper, we study on a Durrmeyer variant of Bernstein-Stancu operators.  We give a Voronovskaja-type theorem for these type operators.

The Voronovskaja type theorem for an extension of Szász-Mirakjan operators

Demonstratio Mathematica, 2012
Recently, C. Mortici defined a class of linear and positive operators depending on a certain function ϕ, which generalize the well known Szász-Mirakjan operators.

Some Approximation Properties of the p,q–Stancu–Schurer–Bleimann–Butzer–Hahn Operators

Journal of Mathematics
In this article, the p,q–Stancu–Schurer–Bleimann–Butzer–Hahn (p,q-SSBBH) operators are introduced. The Korovkin-type theorem is obtained to show the approximation properties of these operators.

A note on the Voronovskaja theorem for Mellin-Fejer convolution operators [PDF]

Applied Mathematics Letters, 2011
Here, using Mellin derivatives and a different notion of moment, we state a Voronovskaja approximation formula for a class of Mellin–Fejer type convolution operators.

Asymptotic formula in simultaneous approximation for certain Ismail-May-Baskakov operators

Journal of Numerical Analysis and Approximation Theory, 2021
In the present paper, we introduce a modification of Ismail-May operators having weights of Baskakov basis functions. We estimate weighted Korovkin's theorem and difference estimates between two operators and establish a Voronovskaja type asymptotic ...

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.

On Better Approximation of the Squared Bernstein Polynomials [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2022
The present paper is defined a new better approximation of the squared Bernstein polynomials. This better approximation has been built on a positive function  defined on the interval [0,1] which has some properties.
