Approximation of $(\bar \psi ,\bar \beta )$ -differentiable periodic functions of many variables
Best-approximation estimates are obtained in the integral and uniform metric on classes of periodic functions of many variables, which are defined by restrictions imposed on the mixed generalized derivative introduced by Stepanets. In this case, theharmonic of trigonometric polynomials, which are us...
