Best<em class="a-plus-plus">m</em>-term trigonometric approximations of classes of (Ψ, β)-differentiable functions of one variable

  • A. S. Fedorenko

Abstract

We obtain an estimate exact in order for the best trigonometric approximation of classes \(L_{\beta ,p}^\psi \) of functions of one variable in the spaceL q in the case where 1<p≤2≤q<∞.
