We compute the exact values of widths for various widths for the classes Wq,a(r)(Φ, μ), μ ≥ 1, of analytic functions in the disk belonging to the Hardy space Hq, q ≥ 1, whose averaged moduli of continuity of the boundary values of the derivatives with respect to the argument fa(r), r ∈ N, are dominated by a given function Φ. For calculating the linear and Gelfand n-widths, we use best linear approximation for these functions.
