Topological Lensing in Spherical Spaces
... On the other hand, spherical topologies may be easily detectable, because for a given value of the curvature radius, spherical spaces can be as small as desired. There is no lower bound on their volumes, because in spherical geometry increasing a manifold’s complexity decreases its volume, in contra ...
