Uniform approximation of Poisson integrals of functions from the class H ω by de la Vallée Poussin sums

Abstract

We obtain asymptotic equalities for least upper bounds of deviations in the uniform metric of de la Vall��e Poussin sums on the sets C^{q}_��H_��of Poisson integrals of functions from the class H_��generated by convex upwards moduli of continuity ��(t) which satisfy the condition ��(t)/t\to\infty as t\to 0. As an implication, a solution of the Kolmogorov-Nikol'skii problem for de la Vall��e Poussin sums on the sets of Poisson integrals of functions belonging to Lipschitz classes H^��, 0
