Widths and entropy numbers of embeddings of Sobolev classes on a H\"{o}lder domain

Functional Analysis 2025-12-02 v1

Abstract

In the present paper we improve Besov's recent result about upper estimates for the entropy numbers of Sobolev classes on a H\"{o}lder domain (in the case when the definition of the Sobolev class involves all partial derivatives of order rr). We also obtain upper estimates for the Kolmogorov, linear and the Gelfand widths.
