本文研究了从Orlicz序列空间lM到一般Banach空间的有界线性算子空间L(lM,X)上的光滑点.利用Orlicz空间上有界线性泛函的特征表示,证明了ExtB(IM)CExtB(lM^**),给出了L(lM,X)单位球上光滑点的刻画,这些结果推广了Grzaslewicz和Younis的相应结果.
In this paper, we study smooth points of the unit ball of L(lM, X). By using the character representation of bounded linear functionals of lM, we prove that ExtB(1M) CExtB(lM**) and give the characterization of the smooth points of the unit ball of K(lM,X), which generalize corresponding results of Grzslewicz and Younis.
