利用HaMy—Litflewood极大函数、光滑模、N-函数的凸性及Holder不等式等工具,讨论了以第二类Chebyshev多项式的零点为插值结点纽的Hermite插值算子在0flicz空间内的逼近性质,得到了逼近阶的一种估计.
The approximation properties of Hermite interpolation operator in Orlicz space by using the zeros of Chebyshev polynomials of the second kind are discussed by using the tool Hardy-Littlewood great function, optical sliding mode, convexity of N -function and holder inequality.
