Weighted Lp Error of Lagrange InterpolationJournal of Approximation Theory - Tập 82 - Trang 321 - 1995
G. Mastroianni, P. Vertesi
The authors give new error estimates of Lagrange interpolation in the weighted Lp, u norm, when u is a generalized Jacobi weight and the interpolation points are the zeros of polynomials orthogonal with respect to (another) generalized Jacobi weight.
