On the limits of Lagrange projectors
In this paper the author answers a question of \textit{C. de Boor} [in: Constructive theory of functions, Varna, 2005, pp. 51--63, Marin Drinov Academic, Sofia (2006)]: What ideal projectors are the limits of Lagrange projectors? The author says about the question that, for every ideal projector \(P\), he prescribes finitely many computations which determine whether the projector \(P\) is a limit of Lagrange projectors.
