Title
Widths of embeddings of 2-microlocal Besov spaces.
Abstract
We consider the asymptotic behavior of the approximation, Gelfand and Kolmogorov numbers of compact embeddings between 2-microlocal Besov spaces with weights defined in terms of the distance to a d-set U⊂Rn. The sharp estimates are shown in most cases, where the quasi-Banach setting is included.
