Two discs and a missing triangle: the maximally extended Kerr black hole revisited
Malcolm A. H. MacCallum
The region spaning the ring singularity in the Kerr black hole solution is described here as two (flat) discs rather than one. From this viewpoint it follows that the usual depicti…
Shearfree Cylindrical Gravitational Collapse
A. di Prisco, L. Herrera, M. A. H. MacCallum +1
We consider diagonal cylindrically symmetric metrics, with an interior representing a general non-rotating fluid with anisotropic pressures. An exterior vacuum Einstein-Rosen space…
On the Matching Conditions for the Collapsing Cylinder
L. Herrera, M. A. H. MacCallum, N. O. Santos
We review the matching conditions for a collapsing anisotropic cylindrical perfect fluid, recently discussed in the literature (2005 {\it Class. Quantum Grav.} {\bf 22} 2407). It i…
Stationary and static cylindrically symmetric Einstein spaces of the Lewis form
M. A. H. MacCallum, N. O. Santos
The derivation of the general solutions for stationary and static cylindrically symmetric Einstein spaces of Lewis form is revisited and the physical and geometrical meaning of the…
