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

Journal 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 ...

Approximation by Bivariate Bernstein-Durrmeyer Operators on a Triangle [PDF]

, 2017
In the present paper, we obtain some approximation properties for the bivariate Bernstein-Durrmeyer operators on a triangle. We characterize the rate of convergence in terms of K−functional and the usual and second order modulus of continuity.

Nonlinear sampling Durrmeyer operators: approximation results in function spaces

Advanced Nonlinear Studies
In this paper we introduce and study the nonlinear version of sampling Durrmeyer operators. For what concerns the space of continuous functions, a pointwise and uniform convergence theorem have been established.

Strong Converse Results for Linking Operators and Convex Functions

Journal 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).

Approximation of Durrmeyer Type Operators Depending on Certain Parameters

Abstract 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

Journal 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.

GBS Operators of LupaAY-Durrmeyer Type Based on Polya Distribution

, 2016
In this paper, we study an extension of the bivariate LupaAY-Durrmeyer operators based on Polya distribution. For these operators we get a Voronovskaja type theorem and the order of approximation using Peetre's K-functional.

Multivariate Bernstein–Durrmeyer operators with arbitrary weight functions [PDF]

, 2010
In this paper we introduce a class of Bernstein–Durrmeyer operators with respect to an arbitrary measure ρ on the d-dimensional simplex, and a class of more general polynomial integral operators with a kernel function involving the Bernstein basis ...
