Optimal interval length for the collocation of the Newton basis
J. M. Carnicer, Y. Khiar, J. M. Peña
It is known that the Lagrange interpolation problem at equidistant nodes is ill-conditioned. We explore the influence of the interval length in the computation of divided differenc…

Observations on interpolation by total degree polynomials in two variables
Jesús Carnicer, Tomas Sauer
In contrast to the univariate case, interpolation with polynomials of a given maximal total degree is not always possible even if the number of interpolation points and the space d…
