摘要
利用单位球的切片定义Banach空间的ω-drop凸性,证明ω-drop凸空间是ω-强光滑的对偶空间,并给出ω-drop凸空间的一些性质.
By using the slice of unit ball, we define ω- drop convex of Banach space uniformly and concisely. We show that the co - drop convex space is the duality of ω - strong smooth space and discuss the properties of the ω- drop convex. At last, we discuss the ω- strong convex in product space lp(Xi) .
