Order estimates of approximation characteristics of functions from anisotropic Nikol'skii-Besov classes
S. Ya. Yanchenko
We obtained exact order estimates of the deviation of functions from anisotropic Nikol'skii-Besov classes from their sections of the Fourie…

The best approximation of functions from anisotropic Nikol'skii-Besov classes defined in
S. Ya. Yanchenko
We establish the exact-order estimates of the best approximations of the functions from anisotropic Nikol'skii-Besov classes of several variables by entire functions in the Lebesgu…
