摘要 对于有界变差函数 f的Durrmeyer B啨zier算子Dn,α(f ,x)在区间 (0 ,1)上收敛于 :1α + 1f(x+ ) + αα + 1f(x -)的收敛阶进行估计 .在Zeng和Chen关于Dn ,α(f ,x)算子的收敛阶研究的基础上 ,对其所估计的结果作进一步的改进 ,得到更精确的系数估计 ,并且所得到的系数估计关于n和x是一致有界的 。 In this paper, we study the approximation of Durrmeyer Bézier Operaters D n,α (f,x) for functions of bounded variation f and obtain a accurate estimation on the rate of convergence of this type. Our result improves the result of Zeng and Chen by giving more exactly and uniformly boundary estimate coefficients.
