得到了以扩充的第一类Chebyshev多项式的零点为插值结点组的Egervary-Turan修正Hermite-Fejer插值多项式在Wiener空间下的平均误差的弱渐进阶.
In this paper, we obtain the weakly asymptotic order for the average error of the Egervary -Turan Hermite-Fejer interpolation based on the extended zeros of Tchebycheff polynomials of the first kind in the Wiener space.
