修正的Hermite-Fejer插值在L_(M,ω)^(Ba)空间中的逼近

Approximation of Modified Hermite-Fejer Interpolation in L_(M,ω)^(Ba) Spaces

在由一列Orlicz空间生成的加权Ba空间中,讨论了两种修正的Hermite-Fejer插值多项式的逼近问题,得到逼近阶的渐近估计结果.

In this paper,the degree of approximation by two kinds of modified Hermite-Fejer polynomials in Ba spaces which are composed of a series of Orlicz spaces was di＇scussed,and the asymptotic estimation results of degree of approximation was obtainted.
