摘要 本文研究了一种修正的Shepard-Lagrange型插值算子在Orlicz空间内的逼近性质,证明了它在Orlicz空间内的有界性,利用光滑模、Hardy-Littlewood极大函数、N函数的凸性及Jensen不等式给出了该算子在Orlicz空间内的逼近度估计. In this paper, the properties of modified Shepard-Lagrange type interpola- tion operator are studied in Orlicz space, the boundedness of the interpolation operator is given, the convex property of N function, Jensen inequality, Hardy-Littlewood great function are used as tools to estimate the approximation of the interpolation operators in Orlicz space.
