Abstract
- In this work, we study superconvergence properties for some high-order orthogonal polynomial interpolations.The results are two-folds: When interpolating function values, we identify those points where the first and second derivatives of the interpolant converge faster;When interpolating the first derivative,we locate those points where the function value of the interpolant superconverges. For the earlier case, we use various Chebyshev polynomials; and for the later case,we also include the counterpart Legendre polynomials.
