KW - Lorentz space, Besov's class, approximation.
AB - <p style="text-align: justify;">In this paper, we consider a Lorentz space with a mixed norm of periodic functions of many variables. We obtain the exact estimation of the best $M$-term approximations of Nikol&#39;skii&#39;s and Besov&#39;s classes in the Lorentz space with the mixed norm.</p>
