Abstract
In this sequel to previous work of A. Stokolos and W. Trebels (1999, J. Approx. Theory 98 , 203–222) we indicate at the example of the Gauss–Weierstrass and the Abel–Poisson means the sharpness of some results obtained there. This is achieved by modifying methods of K. I. Oskolkov (1977, Math. USSR-Sb. 32 , 489–514) and A. A. Soljanik (1986, Ph.D. Thesis, Odessa) developed for the periodic case.
