The Newton Product of Polynomial Projectors. Part 2 : approximation properties
François Bertrand, Jean-Paul Calvi
We prove that the Newton product of efficient polynomial projectors is still efficient. Various polynomial approximation theorems are established involving Newton product projector…
On the Continuity of Multivariate Lagrange Interpolation at Chung-Yao Lattices
Jean-Paul Calvi, Phung Van Manh
We give a natural geometric condition that ensures that sequences of Chung-Yao interpolation polynomials (of fixed degree) of sufficiently differentiable functions converge to a Ta…
Polynomial Interpolation and Approximation in C^d
T. Bloom, L. P. Bos, J. -P. Calvi +1
We update the state of the subject approximately 20 years after the publication of a previous article on this topic. This report is mostly a survey, with a sprinkling of assorted n…
Geometric Weakly Admissible Meshes, Discrete Least Squares Approximations and Approximate Fekete Points
Len Bos, Jean-Paul Calvi, Norm Levenberg +2
Using the concept of Geometric Weakly Admissible Meshes together with an algorithm based on the classical QR factorization of matrices, we compute efficient points for discrete mul…
