Accelerating Convergence of Univariate and Bivariate Fourier ApproximationsManfred Tasche (1) Universität Rostock, Germany
Some new results concerning the accelerating convergence of univarlate and bivariate Fourier expansions are presented. The rate of convergence is estimated with respect to the uniform norm.This acceleration method is a combination of algebraic and trigonometric approximation. Note that the abstract Taylor formula is an essential tool of this approach.
Keywords: Trigonometric approximation and interpolation, Krylov-Lanczos method, accelerating convergence of Fourier expansions
