Sharpening of the estimates for relative widths of classes of differentiable functions
- 22 Downloads
We improve the earlier obtained upper estimates for the least value of the coefficient M for which the Kolmogorov widths d n (W C r , C) of the function class W C r are equal to the relative widths K n (W C r , MW C j , C) of the class W C r with respect to the class MW C j , j < r.
