Estimates for the Kolmogorov widths of the Nikol’skii–Besov–Amanov classes in the Lorentz space

Abstract

The Lorentz space with anisotropic norm of periodic functions of several variables is considered. Estimates for the Kolmogorov widths of the Nikol’skii–Besov–Amanov classes in the Lorentz space with anisotropic norm are found.
