Type: article
Abstract: Exact in order estimates are obtained for the best $m$-term trigonometric approximations of the classes of periodic multivariate functions of mixed smoothness (Nikol'skii-Besov $B^{\boldsymbol{r}}_{p, \theta}$ and Sobolev $W^{\boldsymbol{r}}_{p,\boldsymbol{\alpha}}$ classes) in the space $B_{q,1}$, $2\leq p
