The Effect of Quadrature Errors in the Computation of L^2 Piecewise Polynomial Approximations [PDF]

open access: yes, 1976
In this paper we investigate the L^2 piecewise polynomial approximation problem. L^2 bounds for the derivatives of the error in approximating sufficiently smooth functions by polynomial splines follow immediately from the analogous results for polynomial

Spectral characteristics of two parameter fifth degree polynomial convolution kernel [PDF]

open access: yesBulletin of Natural Sciences Research, 2022
In this paper, the spectral characteristic of a polynomial two parameter convolutional fifth-order interpolation kernel is determined. The spectral characteristic is determined as follows. First, the kernel is decomposed into components.

Equidistribution of the Fekete points on the sphere [PDF]

open access: yes, 2007
The Fekete points are the points that maximize a Vandermonde-type determinant that appears in the polynomial Lagrange interpolation formula. They are well suited points for interpolation formulas and numerical integration.
