摘要
利用Ditzian-Totik光滑模,研究了一类新型的Bernstein算子的逼近性质。根据经典的Bojanic-Cheng分解方法,结合分析技术,讨论了该算子对一类导数为有界变差的函数类的逼近,所得结果推广了Bojanic-Cheng的研究工作。
A direct approximation was established by means of the Ditzian-Totik modulus of smoothness.By using Bojanic-Cheng s method and analysis techniques,this paper studied the rate of convergence of this type operators for some absolutely continuous functions having a derivative equivalent to a bounded variation.The research promotes the work of Bojanic-Cheng.
