Properties of a Two-Sphere Singularity
Deborah A. Konkowski, Thomas M. Helliwell
Recently Böhmer and Lobo have shown that a metric due to Florides can be extended to reveal a classical singularity that has the form of a two-sphere. Here we discuss and expand on…
A Summary: Quantum Singularities in Static and Conformally Static Spacetimes
Deborah A. Konkowski, Thomas M. Helliwell
This is a summary of how the definition of quantum singularity is extended from static space-times to conformally static space-times. Examples are given.
Quantum singularities in spherically symmetric, conformally static spacetimes
T. M. Helliwell, D. A. Konkowski
A definition of quantum singularity for the case of static spacetimes has recently been extended to conformally static spacetimes. Here the theory behind quantum singularities in c…
Quantum singularities in conformally static spacetimes
Deborah A. Konkowski, Thomas M. Helliwell
After a brief review of the standard definition and analysis of classical singularities in general relativistic spacetimes, and of quantum singularities in static spacetimes with t…
Quantum singularities in static and conformally static space-times
D. A. Konkowski, T. M. Helliwell
The definition of quantum singularity is extended from static space-times to conformally static space-times. After the usual definitions of classical and quantum singularities are…
"Singularities" in spacetimes with diverging higher-order curvature invariants
D. A. Konkowski, T. M. Helliwell
After reviewing the definitions of classical and quantum singularities, it is shown by example that if zeroth-order curvature invariants are regular, a diverging higher-order curva…
