关于Kantorovich算子对有界变差函数的导数逼近

On the Derivative Approximation to the Function of Bounded Variation By Kantorovich Operator

本文讨论了Kantorovich算子的导数K_n(F;X)对有界变差函数f′(x)的逼近情况,给出了收敛速度。

In this paper, we discuss the dcrivatc of Kantorovich operator Kn(f, x)to the approximation information of the function of bounded variation f '(x), and gives the degree order.
