Approximation of Classes of Analytic Functions by Fourier Sums in Uniform Metric
Abstract
We find asymptotic equalities for upper bounds of approximations by Fourier partial sums in a uniform metric on classes of Poisson integrals of periodic functions belonging to unit balls of spaces Lp,1≤p≤∞. We generalize the results obtained to classes of (ψ,¯β)-differentiable functions (in the Stepanets sense) that admit analytical extension to a fixed strip of the complex plane.Downloads
