Using ideas of Gru nwald, Marcinkiewicz, and Ve rtesi 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 everywher
Abetrect. I n the present note we give a simple and short proof of the following refinement of the GELFAND-RAIKOV theorem due to M. E. WALTER [2]: Given a locally compact group G and two elements xl, z g E G, neither of which is the identity e of G, then there exists a continuous, imedocible, unitar
