摘要
Given a -function f on a compact riemannian manifold (X,g) we give a set of frequencies depending on a small parameter such that the relative L (2)-error is bounded above by , where f (L) denotes the L-partial sum of the Fourier series f with respect to an orthonormal basis of L (2)(X) constituted by eigenfunctions of the Laplacian operator Delta associated to the metric g.
