Abstract:
In this article, we study some geometrical properties of subsets in  as a differentiable manifold with focal points. We also define some concepts in comparison with its similar ones in both Euclidean space  and a Riemannian manifold without focal points  such as supporting element, convex hull, exposed points and extreme points. |
| Keywords and phrases: sphere  convex sets, strictly convex sets, supporting element, convex hull, exposed points, extreme points. |
