Approximation of classes of analytic functions by de la Vallée Poussin sums in uniform metric
In this paper asymptotic equalities are found for the least upper bounds of deviations in the uniform metric of de la Vallée Poussin sums on classes of 2π-periodic (ψ, β)-differentiable functions admitting an analytic continuation into the given strip of the complex plane. As a consequence, asymp...
