# Trigonometric widths of classes of periodic functions of many variables

Derev’yanko N. V.

Abstract

We obtain exact-order estimates for the trigonometric widths of the classes $B^{\Omega}_{p\theta}$ of periodic functions of many variables in the space $L_q$ for some relations between the parameters $p$ and $q$.
