The Lorentz space with anisotropic norm of periodic functions of several variables is considered. Estimate for the Kolmogorov widths of the Nikol'skii — Besov — Amanov classes in the Lorentz space with anisotropic norm are found.
Keywords: lorentz space, kolmogorov width.
Mots-clés : nikol'skii-besov class
