关于函数及其导数用Bernstein-Durrmeyer算子的同时逼近

On the Simultaneous Approximation of Functions and Their Derivatives by the Bernstein-Durrmeyer Operators

本文利用点态连续模研究了Ｂｅｒｎｓｔｅｉｎ－Ｄｕｒｒｍｅｙｅｒ算子的同时逼近，推广了关于有界变差函数和连续函数的结果．

Using the pointwise modulus of continuity, we discussed the simultaneous approximation for Bernstein-Durrmeyer operators. The results include the results on functions of bounded variation and continuous functions.
