Boundary Set
A (symmetrical) boundary set of Radius 
and center 
is the set of all points 
such that
Let
be the Origin. In 
, the boundary set is then the pair of points 
and 
. In
, the boundary set is a Circle. In 
, the boundary set is a Sphere.See also Circle, Disk, Open Set, Sphere- Geodesic Flow
