Two-Level-Split Decomposition of Anisotropic Besov Spaces
نویسندگان
چکیده
Anisotropic Besov spaces (B-spaces) are developed based on anisotropic multilevel ellipsoid covers (dilations) of R. This extends earlier results on anisotropic Besov spaces. Furthermore, sequences of anisotropic bases are constructed and utilized for two-level-split decompositions of the B-spaces and nonlinear m-term approximation.

Anisotropic Smoothness Spaces via Level Sets
It has been understood for sometime that the classical smoothness spaces, such as the Sobolev and Besov classes, are not satisfactory for certain problems in image processing and nonlinear PDEs. Their deficiency lies in their isotropy. Functions in these smoothness spaces must be simultaneously smooth in all directions. The anisotropic generalizations of these spaces also have the deficiency th...
متن کاملA quarkonial decomposition of Besov-Morrey spaces and Triebel-Lizorkin-Morrey spaces
The aim of this paper is to define the Besov-Morrey spaces and the TriebelLizorkin-Morrey spaces and to present a decomposition of functions belonging to these spaces. Our results contain an answer to the conjecture proposed by Mazzucato.
متن کاملA Mean Characterization of Weighted Anisotropic Besov and Triebel-Lizorkin Spaces
In this article, the authors study weighted anisotropic Besov and TriebelLizorkin spaces associated with expansive dilations and A∞ weights. The authors show that elements of these spaces are locally integrable when the smoothness parameter α is positive. The authors also characterize these spaces for small values of α in terms of a mean square function recently introduced in the context of Sob...

We prove embedding theorems for fully anisotropic Besov spaces. More concrete, inequalities between modulus of continuity in different metrics and of Sobolev type are obtained. Our goal is to get sharp estimates for some anisotropic cases previously unconsidered.
متن کاملTraces of Anisotropic Besov-lizorkin-triebel Spaces—a Complete Treatment of the Borderline Cases
Including the previously untreated borderline cases, the trace spaces (in the distributional sense) of the Besov-Lizorkin-Triebel spaces are determined for the anisotropic (or quasi-homogeneous) version of these classes. The ranges of the traces are in all cases shown to be approximation spaces, and these are shown to be different from the usual spaces precisely in the cases previously untreate...
