凸集的拟端点与Banach空间的k-严格凸性

Ouasi-Extreme Points of Convex Sets and k-Strict Convexity in Banach Spaces

提出凸集拟端点的概念 ,利用它给出Banach空间的k

In this paper, the concept of quasi extreme points of convex sets is provided. By using this concept, we give a equivalent definition of k strict convexity in Banach spaces.
