Estimates of approximative characteristics of the classes B p , θ Ω $$ {B}_{p,\theta}^{\Omega} $$ of periodic functions of many variables with given majorant of mixed continuity moduli in the space L ∞

Abstract

We obtain exact-order estimates of the approximation of the classes \( {B}_{p,\theta}^{\Omega} \) of periodic functions of several variables in the space L ∞ , by using operators of orthogonal projection, as well as linear operators subjected to some conditions.
