Keywords:
entropy numbers; weighted Sobolev spaces; Orlicz spaces; Sobolev spaces; weights; approximation and entropy numbers
Summary:
Upper estimates are obtained for approximation and entropy numbers of the embeddings of weighted Sobolev spaces into appropriate weighted Orlicz spaces. Results are given when the underlying space domain is bounded and for certain unbounded domains.
