The combined Shepard operator of inverse quadratic and inverse multiquadric type [PDF]
, 2022 Starting with the classical, the modified and the iterative Shepard methods, we construct some new Shepard type operators, using the inverse qua- dratic and the inverse multiquadric radial basis functions.

Constrained visualisation using Shepard-Bernoulli interpolation operator [PDF]
, 2020 We consider Shepard-Bernoulli operator in order to solve a problem of interpolation of scattered data that is constrained to preserve positivity, using the technique described by K.W. Brodlie, M.R. Asim and K. Unsworth (2005). We also give some numerical

, 2022 In this paper we investigate the approximation properties for the iterated Boolean sums of Bernstein operators. The approximation behaviour of those operators is presented by the so-called strong inequalities. Moreover, such strong inequalities are valid

Strict positive definiteness on spheres via disk polynomials
International Journal of Mathematics and Mathematical Sciences, Volume 31, Issue 12, Page 715-724, 2002., 2002 We characterize complex strictly positive definite functions on spheres in two cases, the unit sphere of ℂq, q ≥ 3, and the unit sphere of the complex ℓ2. The results depend upon the Fourier‐like expansion of the functions in terms of disk polynomials and, among other things, they enlarge the classes of strictly positive definite functions on real ...

A note on the rate of convergence for Chebyshev-Lobatto and Radau systems
Open Mathematics, 2016 This paper is devoted to Hermite interpolation with Chebyshev-Lobatto and Chebyshev-Radau nodal points. The aim of this piece of work is to establish the rate of convergence for some types of smooth functions.

Rational Quasi-Interpolation Approximation of Scattered Data in R3
Numerical Mathematics: Theory, Methods and Applications, 2018 This paper is concerned with a piecewise smooth rational quasi-interpolation with algebraic accuracy of degree (n + 1) to approximate the scattered data in R. We firstly use the modified Taylor expansion to expand the mean value coordinates interpolation

Integral representations for Padé‐type operators
Journal of Applied Mathematics, Volume 2, Issue 2, Page 51-69, 2002., 2002 The main purpose of this paper is to consider an explicit form of the Padé‐type operators. To do so, we consider the representation of Padé‐type approximants to the Fourier series of the harmonic functions in the open disk and of the L p‐functions on the circle by means of integral formulas, and, then we define the corresponding Padé‐type operators. We

Stečkin inequalities for summability methods
International Journal of Mathematics and Mathematical Sciences, Volume 20, Issue 1, Page 93-100, 1997., 1995 Stečkin proved an inequality on Fejér means of Fourier series He said, “Proving similar inequality for other summability method is an interesting problem.” We generalize Stečkin′s inequality and give various applications to summability methods.

Study Of Hermite-Fejer Type Interpolation Polynomial
, 2021 Given and n points (node) in , the Hermite-Fejer type (HFT) interpolation polynomial is the polynomial of degree at most (2n-1) that agree with and has zero derivative at each of the nodes.

The growth, spread, and mutation of internet phenomena: A study of memes
Results in Applied Mathematics, 2020 An internet memes is defined as “an image, video, piece of text, etc., typically humorous in nature, that is copied and spread rapidly by Internet users, often with slight variations” (Oxford Living Dictionary, 2018). Such units of information are spread
