本文证明了赋范线性空间中闭弱拟凸集必为凸集，并指出郭元明的”弱拟凸集的一些性质及其应用”、“广义凸集的联合逼近特性”两文中的主要结论实质上是已知的结果.

This note concerns two papers by Guo Yuanming[1,2]. By introducing the concept of solar point, and by proving that each closed weak quasi-convex set must be convex in normed linear spaces, we point out that the main theorems contained in [1, 2]
