Approximation of Integrable Functions by Modified Barbosu Operators [PDF]

International Journal of Mathematical, Engineering and Management Sciences
This paper presents an approximation method of integrable functions using a modified Barbosu operator, aimed at improving the rate of convergence in function approximation on the interval [0,1]. By introducing a suitable adjustment in the weight function,

Local approximation properties for certain King type operators

Filomat, 2013
In this paper, we consider a certain King type operators which includes general families of Sz´ asz-Mirakjan, Baskakov, Post-Widder and Stancu operators. By introducing two parameter family of Lipschitz type space, which provides global approximationfortheabovementionedoperators,weobtaintherateofconvergence of this class.

On Baskakov operators preserving the exponential function

Journal of Numerical Analysis and Approximation Theory, 2017
In this paper, we are concerned about the King-type Baskakov operators defined by means of the preserving functions \(e_{0}\) and \(e^{2ax},\ a>0\) fixed.

Quantitative results for the convergence of the iterates of some King type operators [PDF]

Studia Universitatis Babes-Bolyai Matematica, 2019
In this article we construct three \textit{q}-King type operators which fix the functions $e_0$ and $e_2+\alpha e_1$, $\alpha>0$. We study the rates of convergence for the iterates of these operators using the first and the second order modulus of continuity.
