摘要
给出Kantorovich算子 2阶导数与它所逼近的函数的光滑性之间的关系 ,得到Kantorovich算子 2阶导数与Ditzian Totik光滑模的等价定理 .
This paper intends to present the relation of the derivatives of order 2 between Kantorovich operators and the smoothness of the function it approximates ,and obtain the equivalent theorem between the derivatives of roder 2 of Kantorovich operators and the Ditzian Totik modulous of smoothness.
