Error Estimates for Gaussian Quadrature and Weighted-L1 Polynomial Approximation.
Abstract
Error estimates for Gaussian quadrature are given in terms of the number of quadrature points and smoothness properties of the function whose integral is being approximated. An intermediate step involves a weighted-L polynomial approximation problem which is treated in a more general context than that specifically required to estimate the Gaussian quadrature error.
