Rational interpolation with parameters based on Chebyshev nodes

open access: yesFilomat
A type of rational interpolation operator (RIO) with parameter ? is studied in this paper. We give the specific construction of RIO based on Chebyshev nodes of the fourth kind, and calculate the approximation order of the RIO to functions when 1 < ? < 2 and ? > 2 respectively. Furthermore, we analyze the relation between the parameter ?

A novel approach for solving weakly singular fractional integro-differential equations

open access: yesPartial Differential Equations in Applied Mathematics
In this essay, we introduce a novel idea to tackle the challenges of fractional integro-differential equations (FIDEs) featuring weakly singular kernels (WSKs). New idea leverages B-splines for solving such equations, offering a robust numerical solution

Context-Aware Gossip-Based Protocol for Internet of Things Applications

open access: yesSensors, 2018
This paper proposes a gossip-based protocol that utilises a multi-factor weighting function (MFWF) that takes several parameters into account: residual energy, Chebyshev distances to neighbouring nodes and the sink node, node density, and message ...

Bounds for the number of nodes in Chebyshev type quadrature formulas

open access: yesJournal of Approximation Theory, 1991
The authors determine an upper bound for the minimum number of nodes of Chebyshev type quadrature formulas on a finite interval needed in order to achieve a certain degree of precision, using a topological method. The corresponding problem on the \(d\)-dimensional sphere is studied also.

Two Schemes Based on the Collocation Method Using Müntz–Legendre Wavelets for Solving the Fractional Bratu Equation

open access: yesAxioms
Our goal in this work is to solve the fractional Bratu equation, where the fractional derivative is of the Caputo type. As we know, the nonlinearity and derivative of the fractional type are two challenging subjects in solving various equations.

A note on polynomial interpolation at the Chebyshev extrema nodes

open access: yesJournal of Approximation Theory, 1984
Some new properties of the Lebesgue function associated with interpolation at the Chebyshev extrema nodes are established. By estimating the degree of asymmetry of the Lebesgue function in the interval of interest, the estimate of Ehlich and Zeller for the norm of the corresponding interpolation operator is improved.
