Abstract :In this paper, we consider a Lebesgue space with a mixed norm of periodic functions of many variables. We obtain the exact estimation of the best M-term approximations of Nikol’skii’s and Besov’s classes in the Lebesgue space with the mixed norm.Keywords : Lebesgue space, Nikol’skii - Besov class, approximation
