Pseudo -Numbers of Embeddings of Gaussian Weighted Sobolev Spaces
Van Kien Nguyen
In this paper, we study the approximation problem for functions in the Gaussian-weighted Sobolev space of mixed smoothness with error mea…
Pointwise Multipliers for Sobolev and Besov Spaces of Dominating Mixed Smoothness
Van Kien Nguyen, Winfried Sickel
Under certain restrictions we describe the set of all pointwise multipliers in case of Sobolev and Besov spaces of dominating mixed smoothness. In addition we shall give necessary…
Kolmogorov Numbers of Embeddings of Besov Spaces of Dominating Mixed Smoothness into
Van Kien Nguyen
In this paper we shall give two-sided sharp estimates of Kolmogorov numbers of embeddings of the Besov spaces with dominating mixed smoothness into $ L_{\inft…
Bernstein Numbers of Embeddings of Isotropic and Dominating Mixed Besov Spaces
Van Kien Nguyen
The purpose of the present paper is to investigate the decay of Bernstein numbers of the embedding from into the space . The asymptotic be…
Weyl Numbers of Embeddings of Tensor Product Besov Spaces
Van Kien Nguyen, Winfried Sickel
In this paper we investigate the asymptotic behaviour of Weyl numbers of embeddings of tensor product Besov spaces into Lebesgue spaces. These results will be compared with the kno…
