Approximation on a class of Phillips operators generated by q-analogue

Journal of Inequalities and Applications, 2020
The main purpose of this article is to introduce a new generalization of q-Phillips operators generated by Dunkl exponential function. We establish some approximation results for these operators. We also determine the order of approximation, and the rate

Approximation by bivariate Chlodowsky type Szász–Durrmeyer operators and associated GBS operators on weighted spaces

Journal of Inequalities and Applications, 2022
In this article, we consider a bivariate Chlodowsky type Szász–Durrmeyer operators on weighted spaces. We obtain the rate of approximation in connection with the partial and complete modulus of continuity and also for the elements of the Lipschitz type ...

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

Approximate properties of Abel-Poisson integrals on classes of differentiable functions defined by moduli of continuity

Karpatsʹkì Matematičnì Publìkacìï, 2023
The paper deals with the problem of approximation in the uniform metric of $W^{1}H_{\omega}$ classes using one of the classical linear summation methods for Fourier series given by a set of functions of a natural argument, namely, using the Abel-Poisson ...

On the Approximation of Periodic Functions in L2 and the Values of the Widths of Certain Classes of Functions

Моделирование и анализ информационных систем, 2015
The sharp Jackson–Stechkin inequalities are received, in which a special module of continuity Ωem(f;t) determined by Steklov’s function is used instead the usual modulus of continuity of mth order ωm(f;t).

A new kind of Bernstein-Schurer-Stancu-Kantorovich-type operators based on q-integers

Journal of Inequalities and Applications, 2017
Agrawal et al. (Boll. Unione Mat. Ital. 8:169-180, 2015) introduced a Stancu-type Kantorovich modification of the operators proposed by Ren and Zeng (Bull. Korean Math. Soc.

Luzin's condition (N) and modulus of continuity [PDF]

Advances in Calculus of Variations, 2014
Abstract In this paper, we establish Luzin's condition (N) for mappings in certain Sobolev–Orlicz spaces with certain moduli of continuity. Further, given a mapping in these Sobolev–Orlicz spaces, we give bounds on the size of the exceptional set where Luzin's condition (N) may fail.

Approximation results on Dunkl generalization of Phillips operators via q-calculus

Advances in Difference Equations, 2019
The main purpose of this paper is to construct q-Phillips operators generated by Dunkl generalization. We prove several results of Korovkin type and estimate the order of convergence in terms of several moduli of continuity.

Asymptotic estimates for the growth of deformed Hankel transform by modulus of continuity [PDF]

, 2023
We derive asymptotic estimates for the growth of the norm of the deformed Hankel transform on the deformed Hankel-Lipschitz space defined via a generalised modulus of continuity.
