$n$-widths and Approximation theory on Compact Riemannian Manifolds

Functional Analysis 2014-07-15 v2

Abstract

We determine upper asymptotic estimates of Kolmogorov and linear nn-widths of unit balls in Sobolev and Besov norms in LpL_{p}-spaces on compact Riemannian manifolds. The proofs rely on estimates for the near-diagonal localization of the kernels of elliptic operators. We also summarize some of our previous results about approximations by eigenfunctions of elliptic operators on compact homogeneous manifolds.
