Radius estimates for Alexandrov space with boundary
Jian Ge, Ronggang Li
In this note, we study the radius of positively curved or non-negatively curved Alexandrov space with strictly convex boundary, with convexity measured by the Base-Angle defined by…

Rigidity for positively curved Alexandrov spaces with boundary
Jian Ge, Ronggang Li
Inspired by a recent work of Grove-Petersen in [GP18], where the authors studied Alexandrov spaces with largest possible boundary. We study Alexandrov spaces with lower curvature b…
