Szász算子的收敛速度的更精确估计

Accurater Estimates of Convergence of Szász Operator

研究概率型算子Sz偄ｓｚ算子Ｓｎ(f ,x)对有界变差函数的收敛速度估计 ,利用H lder不等式及概率论的方法 ,对该算子的收敛速度估计作进一步改进 ,得到更精确的系数估计。

This thesis makes a new estimation on the rate of convergence of Szász operators for functions of bounded variation. Using Hlder′s inequality and probability method,it makes some improvements on the estimation of the rate of convergence of this operator and achieves an accurater coefficient estimation.
