Parametric Extension of a Certain Family of Summation-Integral Type Operators

Cumhuriyet Science Journal, 2023
In this paper, we introduce a parametric extension of a certain family of summation-integral type operators on the interval [0,∞). Firstly, we obtain test functions and central moments. Secondly, we investigate weighted approximation properties for these

Local and global results for modified Sz\'{a}sz - Mirakjan operators

, 2016
In this paper, we study a natural modification of Sz\'{a}sz - Mirakjan operators. It is shown by discussing many important established results for Sz\'{a}sz - Mirakjan operators.

q-Parametric Bleimann Butzer and Hahn Operators

Journal of Inequalities and Applications, 2008
We introduce a new q-parametric generalization of Bleimann, Butzer, and Hahn operators in C1+x*[0,∞). We study some properties of q-BBH operators and establish the rate of convergence for q-BBH operators.

Convergence and Voronovskaja-type theorems for derivatives of generalized Baskakov operators

Open Mathematics, 2008
Abstract In the present paper our aim is to establish convergence and Voronovskaja-type theorems for first derivatives of generalized Baskakov operators for functions of one and two variables in exponential and polynomial weight spaces.

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 approximation of bivariate functions by modified bivariate operators and GBS operators associated

Journal of Numerical Analysis and Approximation Theory, 2012
In this paper we demonstrate a Voronovskaja-type theorem and approximation theorem for a class of modified operators and Generalized Boolean Sum (GBS) associated operators obtained (see (3)) from given operators.

Dunkl generalization of q-Szász-Mirakjan Kantorovich operators which preserve some test functions

Journal of Inequalities and Applications, 2016
In this paper we introduce q-Szász-Mirakjan-Kantorovich operators generated by a Dunkl generalization of the exponential function and we propose two different modifications of the q-Szász-Mirakjan-Kantorovich operators which preserve some test functions.

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

Journal 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.

Stancu type q-Bernstein operators with shifted knots

Journal of Inequalities and Applications, 2020
In the present paper, Stancu type generalizations of the q-analog of Lupaş Bernstein operators with shifted knots are introduced. Some approximation results and rate of convergence for these operators are investigated.
