On non - Linear approximations of periodic functions of besov classes using greedy algorithms
On non - Linear approximations of periodic functions of besov classes using greedy algorithms
In the present paper, we extend the results of Dinh Dung [5] on non-linear n-term Lq - approximation and non-linear widths to the Besov class p, SB where 1, a given function of modulus of smoothness type.
