Quasi-convex subsets and the farthest direction in Alexandrov spaces with lower curvature bound
Xiaole Su, Hongwei Sun, Yusheng Wang
This paper aims to give a further study on quasi-convex subsets in Alexandrov spaces with lower curvature bound which are introduced in [SSW]. We first provide new insights on quas…

Quasi-convex subsets in Alexandrov spaces with lower curvature bound
Xiaole Su, Hongwei Sun, Yusheng Wang
In this paper, we introduce quasi-convex subsets in Alxandrov spaces with lower curvature bound, which include not only all closed convex subsets without boundary but also all extr…
