A Korovkin Type Approximation Theorem and Its Applications [PDF]

open access: yesAbstract and Applied Analysis, 2014
We present a Korovkin type approximation theorem for a sequence of positive linear operators defined on the space of all real valued continuous and periodic functions via A-statistical approximation, for the rate of the third order Ditzian-Totik modulus ...

New theorems in approximation theory [PDF]

open access: yesمجلة بغداد للعلوم, 2010
The aim of this paper is to prove some results for equivalence of moduli of smoothnes in approximation theory , we used a"non uniform" modulus of smoothness and the weighted Ditzian –Totik moduli of smoothness in by spline functions ,several ...

Blending type approximation by Stancu-Kantorovich operators based on Pólya-Eggenberger distribution

open access: yesOpen Physics, 2017
In the paper the authors introduce the Kantorovich variant of Stancu operators based on Pólya-Eggenberger distribution. By making use of this new operator, we obtain some indispensable auxiliary results.

The Second Ditzian-Totik modulus revisited: refined estimates for positive linear operators [PDF]

open access: yesJournal of Numerical Analysis and Approximation Theory, 2003
Direct theorems for approximation by positive linear operators in terms of the second order Ditzian-Totik modulus of smoothness are proved. Special emphasis is on the magnitude of the absolute constants.

Dunkl analogue of Szász-mirakjan operators of blending type

open access: yesOpen Mathematics, 2018
In the present work, we construct a Dunkl generalization of the modified Szász-Mirakjan operators of integral form defined by Pǎltanea [1]. We study the approximation properties of these operators including weighted Korovkin theorem, the rate of ...

On certain q-Baskakov-Durrmeyer operators [PDF]

open access: yesLe Matematiche, 2011
In this paper we introduce a q−analogue of Baskakaov-beta operators. We establish Voronovskaja-type theorem and obtain local error estimates by these q−operators in uniform norm by using the Ditzian-Totik weighted modulus of smoothness for 0 < q < ...

On Better Approximation of the Squared Bernstein Polynomials [PDF]

open access: yesمجلة 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.

The Approximation of a Modified Baskakov Operator

open access: yesJournal of Mathematics, Volume 2023, Issue 1, 2023., 2023
Because of their simple form and high quality, linear arithmetical operators, particularly linear positive operators, are very popular. The number of in‐depth studies on linear operator approximation is extensive, and the majority of the published material falls into four categories: types and structures of operators, approximation of operators, order ...
