Weighted approximation in mean of classes of analytic functions by algebraic polynomials and finite-dimensional subspaces

  • V. S. Romanyuk


We establish estimates for classic approximation quantities for sets from functional spaces (classes of functions analytic in Jordan domains), namely, for the best polynomial approximations and Kolmogorov widths.
