Operator norms of Gauß-Weierstraß operators and their left quasi interpolants

, 2019
The paper deals with the Gauß–Weierstraß operators Wn and their left quasi interpolants W [r]. The quasi interpolants were defined by Paul Sablonni`ere in 2014.

Localization results for the non-truncated max-product sampling operators based on Fejér and sinc-type kernels

Demonstratio Mathematica, 2016
In this paper, we obtain strong localization results and local direct results in the approximation of continuous functions by the non-truncated max-product sampling operators based on Fejér and sinc (Wittaker)-type kernels.

On the approximation of Kantorovich-type Szàsz-Charlier operators

Demonstratio Mathematica
In this study, we introduce the Kantorovich-type modified Szàsz-Charlier operators and examine their approximation properties within the framework of fractional modeling and control theory. These operators are defined using the Korovkin-type theorem, and

Λ²-statistical convergence and its application to Korovkin second theorem

, 2019
In this paper, we use the notion of strong (N, λ²)−summability to generalize the concept of statistical convergence. We call this new method a λ²−statistical convergence and denote by S λ₂ the set of sequences which are λ²−statistically convergent.

ℐ-αβ-statistical relative uniform convergence for double sequences and its applications

Demonstratio Mathematica
This article introduces a novel concept of convergence, referred to as ℐ{\mathcal{ {\mathcal I} }}-αβ\alpha \beta -statistical relative uniform convergence, for double sequences of functions.

A note on linear compositions of the Mellin convolution operators in the weighted Mellin-Lebesgue spaces

Demonstratio Mathematica
In this article, we express a numerical form of the convergence using the suitable modulus of smoothness for linear compositions of the Mellin convolution operators.

Chlodowsky variant of Bernstein-type operators on the domain

Open Mathematics
In the present paper, we deal with Bernstein-Chlodowsky type operators for approximating functions on the domain. We first present Bernstein-Chlodowsky type operators in two variables and then we discuss some examples of these operators under a domain ...

On the degree of approximation by new Durrmeyer type operators 1

, 2010
In this paper, we define a new kind of positive linear operators and study basic properties as well as Voronovskaya type results. In the last section of this paper we establish the error estimation for simultaneous approximation in terms of higher order ...
