Stancu—Bernstein算子和Stancu—Kantorovich算子对有界变差函数的点态逼近度
On the Rate of Convergence of the Stancu-Bcrnstein Operator and the Stancu-Kantorovich Operator for Function of Bounded Variation
【摘要】 <正> 我们称Pn,s(f,x)为Stancu-Bcrnstcin算子,Qn,s(f,x)称作Stancu-Kantorovich算子。本文研究了Pn,s(f,x)和Qn,s(f,x)对[0,1]的有界变差函数的点态逼近度,主要结果是
【Abstract】 In this paper, the pointwise estimation of the Stance-Bernstein Operator and Stancu-Kantorovich Operator for the function of bounded variation on [0,1] is obtained.
