On the approximation of Kantorovich-type Szàsz-Charlier operators
Demonstratio MathematicaIn this study, we introduce the Kantorovich-type modified Szàsz-Charlier operators and examine their approximation properties within the framework of fractional modeling and control theory. These operators are defined using the Korovkin-type theorem, and

A Note on Weighted Polynomial Approximation with Varying Weights
Journal of Approximation Theory, 1996 The author gives a new (shortened) proof and at the same time a stronger version of a theorem due to \textit{V. Totik} [Weighted approximation with varying weight (1994; Zbl 0808.41001), Theorem 4.1]. The central result of the present paper can be stated as follows: If a sequence of weighted polynomials \(w^np_n\), where \(w\) is an admissible weight ...

Journal of Function Spaces, 2020 We define the notions of weighted λ,μ-statistical convergence of order γ1,γ2 and strongly weighted λ,μ-summability of γ1,γ2 for fuzzy double sequences, where ...

Approximating Steiner Networks with Node Weights [PDF]
SIAM Journal on Computing, 2008 The (undirected) Steiner Network problem is: given a graph G = (V, E) with edge/node weights and edge-connectivity requirements {r(u, v) : u, v ∈ U ⊆ V}, find a minimum weight subgraph H of G containing U so that the uv-edge-connectivity in H is at least r(u, v) for all u, v ∈ U.

New Characterization for Nonlinear Weighted Best Simultaneous Approximation
International Journal of Mathematics and Mathematical Sciences, 2009 This paper is concerned with the problem of a wide class of weighted best simultaneous approximation in normed linear spaces, and it establishes a new characterization result for the class of approximation by virtue of the notion of simultaneous regular ...

Journal of Inequalities and Applications, 2017 In this paper, we establish a link between the Szász-Durrmeyer type operators and multiple Appell polynomials. We study a quantitative-Voronovskaya type theorem in terms of weighted modulus of smoothness using sixth order central moment and Grüss ...

Weighted Approximation for Jackson-Matsuoka Polynomials on the Sphere
Abstract and Applied Analysis, 2012 We consider the best approximation by Jackson-Matsuoka polynomials in the weighted Lp space on the unit sphere of Rd. Using the relation between K-functionals and modulus of smoothness on the sphere, we obtain the direct and inverse estimate of ...

On computing approximate Lewis weights
CoRRIn this note we provide and analyze a simple method that given an $n \times d$ matrix, outputs approximate $\ell_p$-Lewis weights, a natural measure of the importance of the rows with respect to the $\ell_p$ norm, for $p \geq 2$. More precisely, we provide a simple post-processing procedure that turns natural one-sided approximate $\ell_p$-Lewis ...
