Approximation of classes of analytic functions by de la Vallee 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 Vallee Poussin sums on classes of 2\pi-periodic (\psi,\beta)-differentiableExpand

Abstract  We obtain asymptotic equalities for least upper bounds of deviations in the uniform metric of de la Vallee Poussin sums on the sets C β q H ω of Poisson integrals of functions from theExpand
