| Abstract: | Sharp estimates for the approximation numbers of embeddings between the function spacesBspqandFspqon domains are given in a case not thoroughly studied by Edmunds and Triebel. Corresponding sharp estimates are also obtained for the counterparts of that case in the weighted function space setting. |
