Approximation degree of Durrmeyer–Bézier type operators [PDF]

open access: goldJournal of Inequalities and Applications, 2018
Recently, a mixed hybrid operator, generalizing the well-known Phillips operators and Baskakov–Szász type operators, was introduced. In this paper, we study Bézier variant of these new operators.

Degree of Approximation by Hybrid Operators [PDF]

open access: yesAbstract and Applied Analysis, 2013
We consider hybrid (Szász-beta) operators, which are a general sequence of integral type operators including beta function, and we give the degree of approximation by these Szász-beta-Durrmeyer operators.

Degree of Approximation by Rational Functions with Prescribed Numerator Degree [PDF]

open access: bronzeCanadian Journal of Mathematics, 1994
AbstractWe prove a Jackson type theorem for rational functions with prescribed numerator degree: For continuous functions f: [—1,1] —> ℝ with ℓ sign changes in (—1,1), there exists a real rational function Rℓ,n(x) with numerator degree ℓ and denominator degree at most n, that changes sign exactly where f does, and such thatHere C is independent of f,

On the degree of approximation of Fourier series based on a certain class of product deferred summability means

open access: yesJournal of Inequalities and Applications, 2023
In this article, we first introduce and study the basic concepts of deferred Euler and deferred Nörlund product summability means of Fourier series of arbitrary periodic functions.

On Degree of Approximation of Signals in the Generalized Zygmund Class by Using (E, r)(N,q_n) Mean

open access: yesKragujevac Journal of Mathematics, 2023
In the present article, we have established a result on degree of approximation of function (or signal) in the generalized Zygmund class Zl(m),(l ≥ 1) by using (E,r)(N,qn)- mean of Trigonometric Fourier series.

Better degree of approximation by modified Bernstein-Durrmeyer type operators

open access: yesMathematical Foundations of Computing, 2022
In the present article we investigate a Durrmeyer variant of the generalized Bernstein-operators based on a function \begin{document}$ \tau(x), $\end{document} where \begin{document}$ \tau $\end{document} is infinitely differentiable function on \begin ...

Extension of Dasgupta’s Technique for Higher Degree Approximation

open access: yesUniversitas Scientiarum, 2021
In the present paper, rational wedge functions for degree two approximation have been computed over a pentagonal discretization of the domain, by using an analytic approach which is an extension of Dasgupta’s approach for linear approximation.

Heterogeneous pair approximation for voter models on networks [PDF]

open access: yes, 2009
For models whose evolution takes place on a network it is often necessary to augment the mean-field approach by considering explicitly the degree dependence of average quantities (heterogeneous mean-field).

The Rate of Convergence for Linear Shape-Preserving Algorithms

open access: yesConcrete Operators, 2015
We prove some results which give explicit methods for determining an upper bound for the rate of approximation by means of operators preserving a cone. Thenwe obtain some quantitative results on the rate of convergence for some sequences of linear shape ...
