Inhaltsangabe:
- Exact order estimates are obtained of the best $m$-term trigonometric approximations of the Nikol'skii-Besov classes $B^r_{p, θ}$ 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 characteristics on the classes $B^r_{p, θ}$ as well as on the Sobolev classes $W^r_{p, {\boldsymbolα}}$ in the space $B_{\infty,1}$ in the case $1\leq p \leq \infty$.
