Approximation of the periodical functions of high smoothness by the right-angled linear means of Fourier series

We obtain asymptotic equalities for upper bounds of the deviations of the right-angled de la Vallee Poussin sums taken over classes of periodical functions of many variables of high smoothness. These equalities guarantee the solvability of the Kolmogorov-Nikolskii problem for the right-angled de la...
