Abstract
Introduced by G. Birkhoff and popularized by C. de Boor, ideal projectors are an elegant generalization of Hermite interpolation projectors to the multivariate setting. An important class of ideal projectors comprises Lagrange interpolation projectors. In this article, we give a characterization of Lagrange projectors in terms of their “restriction property.”
