Estimates for the entropy numbers of the Nikol'skii-Besov classes of periodic functions of many variables in the space of quasi-continuous functions
A. S. Romanyuk, S. Ya. Yanchenko
We obtained exact-order estimates for the entropy numbers of the Nikol'skii-Besov classes of periodic functions of many variables in the metric of the sp…

On orders of approximation functions of generalized smoothness in Lorentz spaces
G. Akishev
This paper considers the Lorentz space with mixed norm of periodic functions of many variables and of the generalized Nikol'skii -- Besov classes. Estimates for the order of approx…
