Best trigonometric and bilinear approximations for the classes of $(ψ, β)$ -differentiable periodic functions
We establish the exact-order estimates for the best $m$-term trigonometric approximations of the classes $L^{\psi}_{\beta, 1}$ in the space $L_q,\; 2 < q < \infty$. We also determine the exact orders of the best bilinear approximations for the classes of functions of two variables gen...
