Hermite──Fejer插值算子关于导函数的平均收敛性

On Mean Convergence of the Derivatives of Hermite - Fejer Interpolation Operator

讨论以第二类Ｃｈｅｂｙｓｈｅｖ多项式的零点为插值点的Ｈｅｒｍｉｔｅ—Ｆｅｊｅｒ插值算子关于导函数的平均收敛性．

In this paper, the mean convergence of the derivatives of Hermite - Fejer interpolation operator Q2n+1 (f, x ) based on the zeros of Chebyshev polynomial of the second kind is considered. It is mainly shown that
