Approximation by multivariate Baskakov–Durrmeyer operators in Orlicz spaces

open access: yesJournal 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.

On approximation properties of some non-positive Bernstein-Durrmeyer type operators

open access: yesAnalele 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 ...

The q-Chlodowsky and q-Szasz-Durrmeyer Hybrid Operators on Weighted Spaces

open access: yesJournal 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.

Blending type approximation by τ-Baskakov-Durrmeyer type hybrid operators

open access: yesAdvances 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 ] $\tau \in [0,1]$ .

Strong Converse Results for Linking Operators and Convex Functions

open access: yesJournal of Function Spaces, 2020
We consider a family Bn,ρc of operators which is a link between classical Baskakov operators (for ρ=∞) and their genuine Durrmeyer type modification (for ρ=1).

Almost everywhere convergence of orthogonal expansions of several variables

open access: yes, 2003
For weighted $L^1$ space on the unit sphere of $\RR^{d+1}$, in which the weight functions are invariant under finite reflection groups, a maximal function is introduced and used to prove the almost everywhere convergence of orthogonal expansions in $h ...

About a general property for a class of linear positive operators and applications

open access: yesJournal of Numerical Analysis and Approximation Theory, 2005
In this paper we demonstrate a general property for a class of linear positive operators. By particularization, we obtain the convergence and the evaluation for the rate of convergence in term of the first modulus of smoothness for the Bernstein ...

Modified Bernstein Polynomials and Jacobi Polynomials in q-Calculus

open access: yes, 2004
We introduce here a generalization of the modified Bernstein polynomials for Jacobi weights using the $q$-Bernstein basis proposed by G.M. Phillips to generalize classical Bernstein Polynomials.

Approximation of Durrmeyer Type Operators Depending on Certain Parameters

open access: yesAbstract and Applied Analysis, 2017
Motivated by a number of recent investigations, we consider a new analogue of Bernstein-Durrmeyer operators based on certain variants. We derive some approximation properties of these operators.

The generalization of Voronovskaja's theorem for a class of linear and positive operators

open access: yesJournal of Numerical Analysis and Approximation Theory, 2005
In this paper we generalize Voronovskaja's theorem for a class of linear and positive operators, and then, through particular cases, we obtain statements verified by the Bernstein, Schurer, Stancu, Kantorovich and Durrmeyer operators.
