Ukrainian Mathematical Journal Aims and scope

Abstract

We obtain order estimates for linear widths of the Besov classes \(B_{p,{\theta }}^r\) of periodic functions of many variables in the space L q for certain values of parameters p and q different from those considered in the first part of the work.
