AbstractUsing ideas of Grünwald, Marcinkiewicz, and Vértesi concerning the divergence of interpolation processes, a counterexample is constructed which establishes that a Jackson estimate for the best approximation by algebraic polynomials given by Ditzian and Totik is sharp in a pointwise sense everywhere
