Abstract:
      Γ.Ц.Тумаркин established the weighted mean approximation by polynomials to functions of class D on a circle |z| =1. Here we have estimated the degree of weighted mean approximation.C. Я.Алълерestablished the estimation of the degree of mean approximation to functions of class Ep(1p(1≤p<∞) on a rectifiable curve.
