报告题目: Fast construction of the Hermite interpolation and quadrature in Chebyshev points
报告摘要:In this talk, we propose an algorithm for the fast construction of Hermite interpolation in Chebyshev-type points and the corresponding quadrature rules which are extensions of Clenshaw-Curtis rules and Fejer formulas of type I and II. The fast algorithm presented in this talk only needs O(NlogN) operations for N points, which is almost optimal. This fast algorithm is designed by the fast implementation of Fast Fourier Transform, Discrete Sine Transform, Discrete Cosine Transform and their inverse transforms. This fast algorithm may play an important role in constructing numerical quadrature rules and numerical evaluation of integral equations.
