Decomposition of Besov and TriebelLizorkin spaces on the sphere Academic Article uri icon


  • A discrete system of almost exponentially localized elements (needlets) on the n-dimensional unit sphere Sn is constructed. It shown that the needlet system can be used for decomposition of Besov and Triebel-Lizorkin spaces on the sphere. As an application of Besov spaces on Sn, a Jackson estimate for nonlinear m-term approximation from the needlet system is obtained. 2006 Elsevier Inc. All rights reserved.
