点闭凸集是所有有理支撑闭半空间的交
Pointed Closed Convex Sets are the Intersection of All Rational Supporting Closed Halfspaces
摘要：
证明了$\mathbb{R}^n$中的每一个点闭凸集都是包含它的所有有理闭半空间的交，推广了作者以前关于紧凸集的一个结果.
英文摘要：
We prove that every pointed closed convex set in $\mathbb{R}^n$ is the intersection of all the rational closed halfspaces that contain it. This generalizes a previous result by the authors for compact convex sets.
