摘要：

Results on weighted polynomial approximation and interpolation with respect to Freud weights are extended to a more general class of weights. Among others, weights having zeros (Freud-Jacobi type weights) are considered, and a system of nodes is constructed for which the weighted Lebesgue constant of Lagrange interpolation is of optimal order. © 1998, Birkhäuser Verlag, Basel.
