On the Simultaneous Approximation of Functions and Their Derivatives by the Bernstein-Durrmeyer Operators
【摘要】 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.
【Abstract】 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.
