Best approximation of the functions from anisotropic Nikol’skii – Besov classes defined in $R^d$

Yanchenko S. Ya.


Abstract

We establish the exact-order estimates for the best approximations of the functions from anisotropic Nikol’skii – Besov classes of functions of several variables by entire functions in the Lebesgue spaces.
