Approximations of classes of generalized Poisson integrals by Fourier sums in metrics of spaces $L_s$

A. S. Serdyuk, T. A. Stepanyuk

In metrics of spaces $L_s,1\le s\le \infty$, we find asymptotic equalities for upper bounds of approximations by Fourier sums on classes of generalized Poisson integrals of p…
