Upper estimate of the best accuracy of derivative reconstruction based on the values of functions of Besov classes with mixed smoothness

S. N. Kudryavtsev

The work provides an upper estimate of the best accuracy for the problem of reconstructing derivatives based on function values at a given number of points for the functions of Bes…
