Interpolatory band-limited wavelets on the sphere, submitted to Constr. Approx

open access: yes, 2008
In the present paper we construct space-localized bases for the space W n n: = n+s k=n+1 Harmk(S2) of band-limited functions on the sphere. Each of the basis functions is a zonal polynomial centered at a point ηi ∈ S2.

Generalized Taylor Series and Peano Kernel Theorem

open access: yes
As in the polynomial case, non-polynomial divided differences can be viewed as a discrete analog of derivatives. This link between non-polynomial divided differences and derivatives is defined by a generalization of the derivative operator. In this study,

Analysis of Curve Reconstruction by Meshless Parameterization

open access: yes, 2003
: This paper proposes and analyzes a method called meshless parameterization for reconstructing curves from unordered point samples. The method solves a linear system of equations based on convex combinations so as to map the sampled points into ...

Interpolation of Non-Smooth Functions on Anisotropic Finite Element Meshes [PDF]

open access: yes, 1997
. In this paper, several modifications of the quasi-interpolation operator of Scott and Zhang (Math. Comp. 54(1990)190, 483--493) are discussed. The modified operators are defined for non-smooth functions and are suited for the application on anisotropic

Computational aspects of multivariate Polynomial Interpolation

open access: yes, 1995
The paper is concerned with the practical implementation of two methods to compute the solution of polynomial interpolation problems. In addition to a description of the implementation, practical results and several improvements will be discussed ...

Shape Preserving Properties and Convergence of Univariate Multiquadric Quasi-Interpolation

open access: yes, 1994
: With a suitable modification at the endpoints of the range, quasi--interpolation with univariate multiquadrics OE(x) = p c 2 + x 2 is shown to preserve convexity and monotonicity. If h is the maximum distance of centres, convergence of the quasi--
