摘要 对函数的Szász-Bézier算子在区间上的收敛阶进行估计,并在Zeng等人关于Szász-Bézier算子的收敛阶研究的基础上,对其所给的估计结果做进一步的改进,得到更精确的估计式. In this paper, the authors study the approximation of Szasz-Bezier Operaters for functions of bounded variation f and obtain a accurate estimation on the rate of convergence of this type. The result improves the result of Zeng' s by giving more exactly estimate coefficients.
