摘要
We obtain order estimates for the best M-term trigonometric approximations of the classes \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ B^{\Omega }_{{p,{\text{ $ \theta $ }}}} $\end{document} of periodic functions of many variables in the space Lq for several values of the parameters p and q.
