Estimates of characteristics of nonlinear approximation of classes of periodic functions
In the paper we make an overview of results concerning order estimates of the best m-term (sparse) trigonometric approximation and the best orthogonal trigonometric approximation of the Stepanets classes of multi- and univariate functions with bounded generalized derivatives in the Lebesque space. I...
