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.

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 ...

Approximation properties of Kantorovich type q-Balázs-Szabados operators
Demonstratio Mathematica, 2019 In this paper, we introduce a new kind of q-Balázs-Szabados-Kantorovich operators called q-BSK operators. We give a weighted statistical approximation theorem and the rate of convergence of the q-BSK operators.

An Interval‐Valued Fermatean Neutrosophic Framework for Sustainable Transportation Under Uncertainty
Journal of Mathematics, Volume 2026, Issue 1, 2026.Transportation planning is facing heightened complexity because the dynamic parameters influenced by globalization and unpredictable technological disruptions. Traditional models are not capable to handle interval‐based uncertainties related to supply, demand, and costs, especially as the scale of suppliers and customers expands.

Bézier Form of Quantum λ‐Bernstein–Schurer Operators With Associated Approximation Properties
Journal of Mathematics, Volume 2026, Issue 1, 2026.We introduce a Bézier form of Schurer‐type modification of the quantum λ‐Bernstein operators, extending the classical Schurer operators through the Bézier basis with shape parameter −1 ≤ λ ≤ 1. By applying Korovkin’s theorem, we obtain both global and local approximation results.

The Kantorovich form of some extensions for the Szász-Mirakjan operators
Journal of Numerical Analysis and Approximation Theory, 2010 Recently, C. Mortici defined a class of linear and positive operators depending on a certain function \(\varphi\). These operators generalize the well known Szász-Mirakjan operators.

THE KANTOROVICH FORM OF SCHURER-STANCU OPERATORS
Demonstratio Mathematica, 2004 Summary: Considering the given integer \(p\geq 0\) and the given real parameters \(\alpha,\beta\), satisfying \(0\leq\alpha\leq\beta\), in ([7]) was constructed the Schurer-Stancu type operator \(\widetilde S_{m, p}^{(\alpha,\beta)}:C([0,1+p])\to C([0,1])\) defined for any \(f\in C([0,1 +p])\) and any \(m\in\mathbb{N}\) by \[ \bigl( \widetilde S_{m,p}^{

Approximation by Kantorovich type operators
Acta et Commentationes Universitatis Tartuensis de Mathematica, 2003 We study approxiamtion properties of the Kantorovich type operators associated with the Szasz-Mirakyan and Baskakov operators. We prove that the approximation order of smoothness functions by considered operators is better than for the classical Szasz-Mirakyan and Baskakov operators given in [2]. Our paper is motivated by results obtained in [2], [6], [
