Approximation Properties of Durrmeyer Type of (p,q)-Bleimann, Butzer, and Hahn Operators
Journal of Function Spaces, 2019 In this study, we introduce a Durrmeyer type of Bleimann, Butzer, and Hahn operators (BBH) on (p,q)-integers. We derive the some approximation properties for 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.

Inverse theorem for the Szász-Durrmeyer operators
Journal of Numerical Analysis and Approximation Theory, 2009 In the present paper we establish direct and inverse local properties for the Szász-Durrmeyer operators. These operators are introduced in [1] and independently considered in [4] as the generalized integral operators proposed by S.M. Mazhar and V.

Approximation by multivariate Baskakov–Durrmeyer operators in Orlicz spaces
Journal of Inequalities and Applications, 2023 Employing some properties of multivariate Baskakov–Durrmeyer operators and utilizing modified K-functional and a decomposition technique, the authors obtain the direct theorem and weak type inverse theorem in the Orlicz spaces.

Durrmeyer type operators on a simplex
Constructive Mathematical Analysis, 2021 The paper contains the definition and certain approximation properties of a sequence of Durrmeyer-type operators on a simplex, which preserve affine functions and make a link between the multidimensional "genuine" Durrmeyer operators and the multidimensional Bernstein operators.

The q-Chlodowsky and q-Szasz-Durrmeyer Hybrid Operators on Weighted Spaces
Journal of Mathematics, 2020 The main aim of this article is to introduce a new type of q-Chlodowsky and q-Szasz-Durrmeyer hybrid operators on weighted spaces. To this end, we give approximation properties of the modified new q-Hybrid operators.

On approximation properties of some non-positive Bernstein-Durrmeyer type operators
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023 In this paper we shall introduce a new type of Bernstein Durrmeyer operators which are not positive on the entire interval [0, 1]. For these operators we will study the uniform convergence on all continuous functions on [0, 1] as well as a result given ...

On Simultaneous Approximation of Modified Baskakov-Durrmeyer Operators [PDF]
International Journal of Analysis, 2015 We discuss properties of modified Baskakov-Durrmeyer-Stancu (BDS) operators with parameter γ>0. We compute the moments of these modified operators. Also, we establish pointwise convergence, Voronovskaja type asymptotic formula, and an error estimation in terms of second order modification of continuity of the function for the operators Bn,γα,β(f,x).

Blending type approximation by τ-Baskakov-Durrmeyer type hybrid operators
Advances in Difference Equations, 2020 In this work, we construct a Durrmeyer type modification of the τ-Baskakov operators depends on two parameters α > 0 $\alpha >0$ and τ ∈ [ 0 , 1 ] $\tau \in [0,1]$ .
