Order of the trigonometric widths of the Nikol’skii-Besov classes with mixed metric in the metric of anisotropic Lorentz spaces

Order of the trigonometric widths of the Nikol’skii-Besov classes with mixed metric in the metric of anisotropic Lorentz spaces

In this paper we estimate the order of the triginometric width of the Nikol’skii–Besov classes Bατp(Tn) with mixed metric in the anisotropic Lorentz space Lqθ(Tn) when 1
