中文摘要:本文考虑用Tchebycheff-Fourier级数的(F,α)平均逼近函数f∈C[-1,1],在f∈lipβ时得到了误差的表达式,较大地改进了文[1]中的有关结果.
外文摘要:In this paper we consider the approximation of f ∈ C [- 1, 1] by (F,α)means of Tchebycheff-Fourier Series. Mainly. the expressions of error of approximation are obtained when f ∈lipβ. The similar result of Sheng [1] has been improved.
