Approximating fractional calculus operators with general analytic kernel by Stancu variant of modified Bernstein–Kantorovich operators

Mathematical Methods in the Applied Sciences, Volume 47, Issue 5, Page 3809-3825, 30 March 2024.
The main aim of this paper is to approximate the fractional calculus (FC) operator with general analytic kernel by using auxiliary newly defined linear positive operators. For this purpose, we introduce the Stancu variant of modified Bernstein–Kantorovich operators and investigate their simultaneous approximation properties.

Approximation by q‐Post‐Widder Operators Based on a New Parameter

Abstract and Applied Analysis, Volume 2024, Issue 1, 2024.
The purpose of this paper is to introduce q‐Post–Widder operators based on a new parameter and study their approximation properties. The moments and central moments are investigated. And some local approximation properties of these operators by means of modulus of continuity and Peetre’s K‐functional are presented.

THE KANTOROVICH FORM OF SCHURER-STANCU OPERATORS

Demonstratio Mathematica, 2004
Summary: Considering the given integer \(p\geq 0\) and the given real parameters \(\alpha,\beta\), satisfying \(0\leq\alpha\leq\beta\), in ([7]) was constructed the Schurer-Stancu type operator \(\widetilde S_{m, p}^{(\alpha,\beta)}:C([0,1+p])\to C([0,1])\) defined for any \(f\in C([0,1 +p])\) and any \(m\in\mathbb{N}\) by \[ \bigl( \widetilde S_{m,p}^{

A Stancu type extension of Cheney and Sharma operators

Journal of Numerical Analysis and Approximation Theory, 2018
In this paper we deal with a Stancu type extension of the Cheney and Sharma operators. We consider a recurrence relation to get moments of the operators and give a local approximation result via suitable K-functional.

Mixed symmetric baryon multiplets in large $N_c$ QCD: two and three flavours

, 2010
We propose a new method to study mixed symmetric multiplets of baryons in the context of the $1/N_c$ expansion approach. The simplicity of the method allows to better understand the role of various operators acting on spin and flavour degrees of freedom.

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

Journal of Mathematics, Volume 2024, Issue 1, 2024.
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. Then, the rate of convergence of these operators with the help of the modulus of continuity and Lipschitz‐type maximal functions is calculated ...

Quantitative estimates for bivariate Stancu operators

Mathematical Methods in the Applied Sciences, 2018
In this paper, we introduce Voronovskaja‐type and Grüss–Voronovskaja‐ type theorems in quantitative mean with the help of the usual modulus of continuity for bivariate Stancu operators, which are different from a tensor product setting.

Approximation properties of a bivariate Stancu type operator

Journal of Numerical Analysis and Approximation Theory, 2005
An extension of Stancu's operator \(P_{m}^{(\alpha ,\beta )}\) to the case of bivariate functions is presented and some approximation properties of this operator are discussed.

On Kantorovich variant of Brass-Stancu operators

Demonstratio Mathematica
In this study, we deal with Kantorovich-type generalization of the Brass-Stancu operators. For the sequence of these operators, we study Lp{L}^{p}-convergence and give some upper estimates for the Lp{L}^{p}-norm of the approximation error via first-order
