On estimates of the order of the best M–term approximations of functions of several variables in the anisotropic Lorentz – Zygmund space
The article considers the anisotropic Lorentz – Karamata space of periodic functions of several variables and the Nikol'skii – Besov class in this space. The order-sharp estimates are established for the best $M$-term trigonometric approximations of functions fr...
