摘要：

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 subset of R-n. The sharp estimates are shown in most cases, where the quasi-Banach setting is included. (C) 2013 Elsevier Inc. All rights reserved.
