Abstract
In this brief survey special attention is paid to some recent procedures for constructing optimal interpolation processes, i.e., with Lebesgue constant having logarithmic behaviour. A new result on Lagrange interpolation based on the zeros of the associated Jacobi polynomials and on suitable additional nodes is given.File in questo prodotto:
