Rate of convergence of Szász-beta operators based on q-integers

Demonstratio Mathematica, 2017
The purpose of this paper is to establish the rate of convergence in terms of the weighted modulus of continuity and Lipschitz type maximal function for the q-Szász-beta operators. We also study the rate of A-statistical convergence.

Approximation degree of Durrmeyer–Bézier type operators

Journal 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.

On the (p,q)−Stancu Generalization of a Genuine Baskakov-Durrmeyer Type Operators

International Journal of Analysis and Applications, 2017
In this paper, we introduce a Stancu generalization of a genuine Baskakov-Durrmeyer type operators via (p,q)− integer. We investigate approximation properties of these operators.

Approximation Properties of p,q-Szász-Mirakjan-Durrmeyer Operators

Journal of Function Spaces, 2021
In this article, we introduce a new Durrmeyer-type generalization of p,q-Szász-Mirakjan operators using the p,q-gamma function of the second kind. The moments and central moments are obtained.

On generalized Baskakov-Durrmeyer-Stancu type operators

Demonstratio Mathematica, 2017
In this paper, we study some local approximation properties of generalized Baskakov-Durrmeyer-Stancu operators. First, we establish a recurrence relation for the central moments of these operators, then we obtain a local direct result in terms of the ...

Approximation with Chlodowsky variant of Kantorovich-Stancu-operators employing associated λ-polynomials

Journal of Inequalities and Applications
This article explores a Chlodowsky-type extension of the Kantorovich variant of Szász operators based on the associated λ-polynomials. The convergence properties of these operators are established by employing the universal Korovkin-type property, and ...
