The Kerr space-time near the ring singularity
The geometry of the Kerr space-time near the ring singularity is investigated. The ring singularity is either an edge or a self- intersection of the topological space depending on which extension of the metric through \(r=0\) is implemented. The only nonspacelike geodesics which can reach the ring singularity are restricted to the equatorial plane.
