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

In metrics of spaces $L_s,1\le s\le \mathrm{\infty }$, we find asymptotic equalities for upper bounds of approximations by Fourier sums on classes of generalized Poisson integrals of periodic functions, which belong to unit ball of space $L_1$.
