Durrmeyer type (p,q)-Baskakov operators preserving linear functions [PDF]

, 2018
The present paper deals with the construction of Baskakov Durrmeyer operators, which preserve the linear functions, in (p,q)-calculus. More precisely, using (p,q)-Gamma function we introduce genuine mixed type Baskakov Durrmeyer operators having Baskakov

Approximation of Discontinuous Functions by Positive Linear Operators. A Probabilistic Approach

Mathematical Methods in the Applied Sciences, Volume 49, Issue 5, Page 4184-4197, 30 March 2026.
ABSTRACT We obtain approximation results for general positive linear operators satisfying mild conditions, when acting on discontinuous functions and absolutely continuous functions having discontinuous derivatives. The upper bounds, given in terms of a local first modulus of continuity, are best possible, in the sense that we can construct particular ...

Convergence Theorems for Derivatives of a New Baskakov -Type Operators

Wasit Journal for Pure Sciences
The motive of this paper is to introduce and investigate the derivatives of some Baskakov operators. Firstly, we treated with the convergence theorems on some certain type of Baskakov operators and then we found the derivative of these operators.

On the Reducibility of Weighted Composition Operators Generated by Periodic Transformations

International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.
In this article, we study the reducibility of weighted composition operators (also known as weighted displacement operators) acting on Banach spaces of continuous functions on a compact topological space X. We consider operators of the form Bu(x) = a(x)u(α(x)), where α : X⟶X is a continuous mapping and a is a continuous function.

Lp-inverse theorem for modified beta operators

International Journal of Mathematics and Mathematical Sciences, 2003
We obtain a converse theorem for the linear combinations of modified beta operators whose weight function is the Baskakov operators. To prove our inverse theorem, we use the technique of linear approximating method, namely, Steklov mean.

Approximation by (p, q)-Baskakov–Beta operators [PDF]

Applied Mathematics and Computation, 2017
In the present paper, we consider $(p,q)$-analogue of the Baskakov-Beta operators and using it, we estimate some direct results on approximation. Also, we represent the convergence of these operators graphically using MATLAB.

Wavelets‐Associated Approximation to the Family of New Class of q‐Szász Operators Via q‐Analog

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
This study investigates the approximation properties of a recently developed class of q‐Szász–Mirakjan operators integrated with wavelets. By constructing these q‐Szász‐type operators and introducing their Kantorovich variants, we establish Lp‐approximation results for 1 ≤ p ≤ ∞.

Generalized weighted Stechkin–Marchaud-type inequalities for Baskakov–Durrmeyer operators [PDF]

, 2012
In this paper, we introduce new weighted modulus of smoothness ωφβ2(f;t)w,λ and prove the generalization of Stechkin–Marchaud-type inequalities of weighted approximation for Baskakov–Durrmeyer operators, from which the inverse results of Baskakov ...

Integral Modification of Lupaş‐Type Operators for Improved Approximation and Reduced Bias

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this paper, we introduce a generalized class of Lupaş‐type operators constructed through an integral modification of the classical formulation. Instead of using discrete point evaluations, the proposed operators are defined by means of weighted local integral averages together with a parameter‐dependent structure.

Weighted Korovkin‐Type Theorem and Some Properties of Szász–Mirakjan Operators Preserving Exponential Functions via Power Series Statistical Convergence

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this article, we establish a weighted Korovkin‐type approximation theorem within the framework of power series statistical convergence and provide a systematic extension of classical Korovkin theory to weighted function spaces. Furthermore, we investigate the approximation properties of the Szász–Mirakjan operators preserving exponential functions ...
