关于Durrmeyer算子的函数类逼近

On Approximation of Classes of Functions for Durrmeyer Operatorsc

应用概率论的某些结果讨论了Ｄｕｒｒｍｅｙｅｒ算子的函数类逼近，给出了Ｅ（Ｃω（Ｍ），Ｍｎ）和Ｅ（Ｃ（Ｍ，Ｍ１），Ｍｎ）的上、下界估计．

In this note using sonic results of the probability theory, We discuss approximation of classes of functions for Durrmeyer operators. The upper and lower estimates of E(Cω(M),Mn ) and E(C (M,M1 ),Mn ) are given.
