Estimates of approximation characteristics of classes $B^{\Omega}_{p,\theta}$ of periodic functions of several variables with given majorant of the mixed modulo of continuity

Abstract

We obtain exact order estimates of approximation of classes $B^{\Omega}_{p,\theta}$ of periodic functions of several variables in the space $L_q$ by using linear operators subjected to some conditions for some means of parametres $p$ and $q$
