Classical Lagrange Interpolation Based on General Nodal Systems at Perturbed Roots of Unity

Classical Lagrange Interpolation Based on General Nodal Systems at Perturbed Roots of Unity

The aim of this paper is to study the Lagrange interpolation on the unit circle taking only into account the separation properties of the nodal points. The novelty of this paper is that we do not consider nodal systems connected with orthogonal or paraorthogonal polynomials, which is an interesting...
