On a Conjecture of Carl de Boor Regarding the Limits of Lagrange Interpolants
نویسندگان
چکیده
The purpose of this paper is to provide a counterexample to a conjecture of Carl de Boor [2], that every ideal projector is a limit of Lagrange projectors. The counterexample is based on a construction of A. Iarrobino [9] pointed to in this context by G. Ellingsrud (as mentioned in de Boor’s paper [2]). We also show that the conjecture is true for polynomials in two variables.

What Are the Limits of Lagrange Projectors?
The behavior of interpolants as interpolation sites coalesce is explored in the suitably restricted context of multivariate polynomial interpolation. A Lagrange projector Pτ is, by definition, a linear map on some linear space X of (scalar-valued) functions on some domain T that associates each function f ∈ X with the unique element Pτf in ranPτ that agrees with f at a given (finite) set τ . Th...
متن کاملBivariate ideal projectors and their perturbations
In this paper we present a complete description of ideal projectors from the space of bivariate polynomials F[x, y] onto its subspace F<n[x, y] of polynomials of degree less than n. Several applications are given. In particular, we study small perturbations of ideal projectors as well as the limits of Lagrange projectors. The latter results verify one particular case of a conjecture of Carl de ...
متن کاملOn the Limits of Lagrange Projectors
This article addresses a question of Carl de Boor (cf. [3]): What ideal projectors are the limits of Lagrange projectors? The results of this paper answer the question in the sense that for every ideal projector P we prescribe nitely many computations that determine whether the projector P is a limit of Lagrange projectors.
متن کاملApproximation Order without Quasi-Interpolants
In the study of approximation order, particularly in a multivariable setting, quasi-interpolants have played a major role. This report points out some limitations of quasi-interpolants and describes some recent results on approximation order obtained without the benefit of the quasi-interpolant idea. §1. Approximation Order In most general terms, “approximation order” is defined as follows. Def...
