On the Approximation Process of Shifted-Knots Bivariate Stancu-Type Kantorovich Operators

Journal of Mathematics
This paper focuses on defining bivariate Stancu-type Kantorovich operators with the technique associated with the idea of shifted knots. The degree of approximation and weighted approximation of these bivariate operators are estimated, respectively, by ...

Approximation on the sphere by weighted Fourier expansions

Journal of Applied Mathematics, 2005
The main theme of this paper is the approximation on the sphere by weighted sums of spherical harmonics. We give necessary and sufficient conditions on the weights for convergence in both the continuous and the LP cases.

Approximation of the Summation-Integral-Type q-Szász-Mirakjan Operators

Abstract and Applied Analysis, 2012
We introduce summation-integral-type q-Szász-Mirakjan operators and study approximation properties of these operators. We establish local approximation theorem. We give weighted approximation theorem.

The Approximation Characteristics of Weighted Band-Limited Function Space

Mathematics
This article primarily investigates the width problem within weighted band-limited function space in a uniform setting. Through an analysis of the properties of s-numbers, we establish a connection between the widths of weighted band-limited function ...

Harmonic vibration of cusped plates in the N-th approximation of Vekua’s hierarchical models

Archives of Mechanics, 2013
In this paper elastic cusped symmetric prismatic shells (i.e., plates of variable thickness with cusped edges) in the N-th approximation of Vekua’s hierarchical models are considered.

Statistical Deferred Weighted Riemann Summability and Fuzzy Approximation Theorems [PDF]

Sahand Communications in Mathematical Analysis
The notion of statistical convergence has fascinated many researchers due mainly to the fact that it is more general than the well-established hypothesis of ordinary (classical) convergence.

Approximation Algorithms for Multicoloring Planar Graphs and Powers of Square and Triangular Meshes

Discrete Mathematics & Theoretical Computer Science, 2006
A multicoloring of a weighted graph G is an assignment of sets of colors to the vertices of G so that two adjacent vertices receive two disjoint sets of colors. A multicoloring problem on G is to find a multicoloring of G.
