Fourier级数的N—V平均对连续周期函数的逼近

THE APPROXIMATION OF THE N-V MEANS OF THE FOURIER SERIES OF THE CONTINUOUS PERIODIC FUNCTIONS

本文研究Founer级数及其共轭级数的N—V平均对连续周期函数的逼近度,本文定理包括了叶菲莫夫的结果.

In this paper, we consider the approximation degree of the partial sum of the N—V mean of the Fourier series and its conjujate series to the continuous periodic functions, Our theorems contain some results of Eφpuμob[3].
