多面体凸集的一个“隐藏”刻画
A "hidden" characterization of polyhedral convex sets
摘要:
证明了完备线性度量空间$X$的闭凸子集$C$在其闭线性壳中是多面体的当且仅当对于任何不同点$x,y\in A$,没有无穷子集$A\subset X\backslash C$可以在$[x,y]\cap C\not = \emptyset$意义下隐藏在$C$之后.
英文摘要:
We prove that a closed convex subset $C$ of a complete linear metric space $X$ is polyhedral in its closed linear hull if and only if no infinite subset $A\subset X\backslash C$ can be hidden behind $C$ in the sense $[x,y]\cap C\not = \emptyset$ for any distinct points $x,y\in A$.
