Bounds on Kolmogorov widths and sampling recovery for classes with small mixed smoothness
V. Temlyakov, T. Ullrich
Results on asymptotic characteristics of classes of functions with mixed smoothness are obtained in the paper. Our main interest is in estimating the Kolmogorov widths of classes w…

A new upper bound for sampling numbers
Nicolas Nagel, Martin Schäfer, Tino Ullrich
We provide a new upper bound for sampling numbers associated to the compact embedding of a separable reproducing kernel Hilbert space into the space of sq…

How anisotropic mixed smoothness affects the decay of singular numbers of Sobolev embeddings
Thomas Kuehn, Winfried Sickel, Tino Ullrich
We continue the research on the asymptotic and preasymptotic decay of singular numbers for tensor product Hilbert-Sobolev type embeddings in high dimensions with special emphasis o…
