摘要
利用Ditzian-Totik光滑模、二阶连续模和K泛函,研究了一类新型的Baskakov算子的逼近性质.最后讨论了这类算子对Lipschitz函数类的逼近.
The authors establish a direct approximaiton by means of the Ditzian-Totik modulus of smoothness and a global approximation theorem in terms of second order modulus of continuity.The approximation of this new type operators for the Lipschitz class functions are also obtained.
