Baskakov算子对P次有界变差函数的逼近

运用概率论的一些方法和结论 ,运用累次Albel变换得出Baskakov算子对在 [0 ,∞ )的任意有限子区间上具有P≥ 1 次有界变差函数的逼近度估式 .

A Generalization of (0, M) Interpolation

In this paper we introduce a new kind of interpolation of function with period 2π and establish the rate of convergence.The usual Birkhoff interpolation is a special case of our new interpolation as a linnit case.
