摘要
讨论改进的拟Grünwald插值在Wiener空间下的平均误差,得到了其于Lp范数意义下p-平均误差的弱渐近阶,证明了其于Lp范数意义下是收敛算子列.
The average errors of modified quasi-Grünwald interpolation are discussed on Wiener space and weakly asymptotic order for the p-average errors of Lp-norm approximation is obtained.It is proved that the quasi-Grünwald interpolation sequence is convergence operator sequence for Lp-norm approximation.
