Approximation by poised sets of nodes
G. S. Avagyan, L. R. Rafaelyan Chair of Numerical Analysis and Mathematical Modeling YSU, Armenia
Abstract:
In the present paper it has been shown that nodes of any finite set $X\subset\mathbb{R}^d$ can be made independent by arbitrarily small perturbation, in other words, the set $X$ can be approximated by sets of independent nodes. In the case of $\#X=\mathrm{dim}\prod^d_n$ the set $X$ can be approximated by sets of poised nodes.
Keywords:
Lagrange interpolation, independent points, poised sets.
