A new kind of Durrmeyer-Stancu-type operators

Demonstratio Mathematica
The objective of this study is to examine a class of positive linear operators, defined in terms of the bψ,kλ,μ{b}_{\psi ,k}^{\lambda ,\mu } basis and to analyze their approximation properties. Direct estimates for the (λ,μ)\left(\lambda ,\mu )-Durrmeyer-

Some bivariate Durrmeyer operators based on q-integers

, 2017
In the present paper we introduce a q -analogue of the bivariate Durrmeyer operators. A convergence theorem for these operators is established and the rate of convergence in terms of modulus of continuity is determined.

(λ, ψ)-Bernstein-Kantorovich operators

Demonstratio Mathematica
In this article, we introduce a new family of (λ,ψ)\left(\lambda ,\psi )-Bernstein-Kantorovich operators which depends on a parameter λ\lambda , derived from the basis functions of Bézier curves and an integrable function ψ\psi .

On the degree of approximation by modified gamma operators

, 2017
We consider certain linear operators associated with gamma function in polynomial weighted spaces of functions of one variable and study approximation properties of these operators, including theorems on the degree of approximation.

On the generalized Mellin integral operators

Demonstratio Mathematica
In this study, we give a modification of Mellin convolution-type operators. In this way, we obtain the rate of convergence with the modulus of the continuity of the mmth-order Mellin derivative of function ff, but without the derivative of the operator ...

Approximation of functions with linear positive operators which fix {1, φ} and {1, φ2}

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
In this manuscript, linear and positive operators described on bounded and unbounded intervals that fix the function sets {1, φ} and {1, φ2} such that φ ∈ C[0, 1] are presented. Then we present different types of operators by choosing different functions

Rate of Convergence for Ibragimov-Gadjiev-Durrmeyer Operators

Demonstratio Mathematica, 2017
The present paper deals with the rate of convergence of the general class of Durrmeyer operators, which are generalization of Ibragimov-Gadjiev operators. The special cases of the operators include somewell known operators as particular cases viz.

Approximation Properties of Ibragimov-Gadjiev-Durrmeyer Operators on Lp (ℝ+)

Demonstratio Mathematica, 2017
We deal with the approximation properties of a new class of positive linear Durrmeyer type operators which offer a reconstruction of integral type operators including well known Durrmeyer operators.

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.
