Abstract

We study multivariate polynomial interpolation based on Radon projections corresponding to the intersection of hyperplanes and the coordinate axes of \(\mathbb {R}^n\). We give a characterization of these hyperplanes which determine an interpolation polynomial uniquely. We also establish conditions such that the interpolation projectors based on Radon projections converge to the Taylor projector.

基于拉顿投影的多变量多项式插值法
我们基于超平面与 \mathbb {R}^n\ 的坐标轴交点对应的 Radon 投影研究多变量多项式插值。我们给出了这些超平面的特征,它们唯一地决定了插值多项式。我们还建立了基于 Radon 投影的插值投影收敛于泰勒投影的条件。
