Nonlinear approximation of the classes $F_{q,r}^{\psi}$ of functions of several variables in the integral metrics
In the paper, exact order estimates of nonlinear approximative characteristics (such as the best $m$-member of the trigonometric approximation, better than the $m$-th term of the orthogonal trigonometric approximation, approximation of the $m$-member of the grid by polynomials) are found in the clas...
