Freud-Butzer-Hahn type quantitative theorems for probabilistic representations of (C0) operator semigroups

  • Chen Wenzhong
  • Zhou Mi


In this paper, we shall exploit the Freud method in the Classical operator approximation theory to improve known quantitative estimations with an emphasis on Calculah' on the generic constants.
