摘要
本文主要得到了Orlicz空间L_M~*中非空子集C对L_M~*的最佳逼近的特征条件及其特征性质的刻划，即Kolmogorov型特征。所得结论推广了[4][5]中主要结果。
In this paper, We obtain the characterization condition of best approximation elements from an Orlicz space LM to its nonempty subsets C, Moreover, conditions of subsets C to ensure the true of characterization condition are involved. these theorems include the main result of [4,5] as special case.
