Sampling recovery on classes defined by integral operators and sparse approximation with adaptive dictionaries
V. Temlyakov
In this paper we continue to develop the following general approach. We study asymptotic behavior of the errors of sampling recovery not for an individual smoothness class, how it…

Entropy numbers of classes defined by integral operators
V. Temlyakov
In this paper we develop the following general approach. We study asymptotic behavior of the entropy numbers not for an individual smoothness class, how it is usually done, but for…

Some lower bounds for optimal sampling recovery of functions with mixed smoothness
A. Gasnikov, V. Temlyakov
Recently, there was a substantial progress in the problem of sampling recovery on function classes with mixed smoothness. Mostly, it has been done by proving new and sometimes opti…
