The Pointwise Characterization of Higher Derivatives for the Baskaov Operators

本文借助Ditzian Totik光滑模给出Baskakov算子的高阶导数的特征刻画 。

Using the Ditzian-Totik moduli of smoothness, we give the characterization of higher order derivatives for the Baskakov operators. The obtained results in this paper combine the pointwise with global conclusions.
