AI总结:

本文通过证明存在正实数η使得偏导数型实理想投影子P是Lagrange投影子序列的点态极限,验证了Carl de Boor关于理想投影子的猜想,并给出了当Lagrange投影子的值域由其核的Gröbner阶梯(按字典序)张成时计算η的算法。

摘要:

本文通过证明存在正实数η∈R使得偏导数型实理想投影子P是Lagrange投影子序列的点态极限(这些Lagrange投影子是从P扰动得到的,扰动幅度不超过η),验证了Carl de Boor关于理想投影子的猜想。此外,我们提出了一种算法,用于在Lagrange投影子的值域由其核的Gröbner阶梯(按字典序)张成时计算这样的η的值。

英文摘要:

In this paper, we verify Carl de Boor's conjecture on ideal projectors for real ideal projectors of type partial derivative by proving that there exists a positive $η\in \mathbb{R}$ such that a real ideal projector of type partial derivative $P$ is the pointwise limit of a sequence of Lagrange projectors which are perturbed from $P$ up to $η$ in magnitude. Furthermore, we present an algorithm for computing the value of such $η$ when the range of the Lagrange projectors is spanned by the Gröbner éscalier of their kernels w.r.t. lexicographic order.
