摘要
利用经典的Zeng分解方法,并结合Bleimann-Butzer and Hahn算子基函数的界,讨论了Bleimann-Butzer and Hahn-Bézier算子在0<α<1时对一般有界函数的逼近,得到比较好的收敛阶估计,所得结果拓展了在α≥1时对有界变差函数逼近的研究工作.
In this paper the pointwise approximation of the B6zier variant of Bleimann-Butzer and Hahn operators for bounded functions is studied in the case of 0〈α〈l. By using the method of Zeng and some analysis techniques, we obtain an estimate formula on the b6zier type operators. Our results extend the work of the approximation within α≥l for functions of bounded variation.
