Approximation of analytic functions by repeated de la Vallee Poussin sums

Approximation of analytic functions by repeated de la Vallee Poussin sums

The paper deals with the problems of approximation of periodic functions of high smoothness by arithmetic means of Fourier sums. The simplest and natural example of a linear process of approximation of continuous periodic functions of a real variable is the approximation of these functions by partia...
