The best $m$-term trigonometric approximations of the classes of periodic functions of one and many variables in the space $B_{q,1}$
Exact order estimates are obtained of the best $m$-term trigonometric approximations of the Nikol'skii-Besov classes $B^r_{p, \theta}$ of periodic functions of one and many variables in the space $B_{q,1}$. In the univariate case ($d=1$), we get the orders of the respective approximation charac...
