摘要 运用逼近论的一些方法和技巧,研究了一元Bleimann-Butzer-Hahn算子对有界变差函数的逼近,得到了对该函数类的点态逼近度估计的逼近定理. Using some results and methods of aproximation, this paper studies the approximation of Bleimann-Butzer-Hahn operators for functions of bounded variation, and the pointwise convergence theorem of these operstors are obtained.
